To avoid finding it difficult to understand the concepts and formulas of this subject, students must start practising the problems on a daily basis beforehand while referring to RS Aggarwal Solutions Class 10 Chapter 4 Quadratic Equations - Ex 4A, which is available in a PDF format on Vedantu's site. This PDF will give students a detailed overview of the chapter. Students will gain knowledge on different concepts of a Quadratic Equation such as:

 

Meaning of Quadratic Equations

Quadratic equations are considered the polynomial equations of degree 2 in one variable if type f(x) = ax2 + bx + c where a, b, c belong to (∈) R and a ≠ 0. This is considered as the general form of a quadratic equation where 'a' is referred to as the leading coefficient, and 'c' is known to be the absolute term of f(x). The values of x that are responsible for satisfying the quadratic equation are known as the roots of the quadratic equation (a,b). The quadratic equation will always have two roots. The nature of roots might be real or imaginary.

 

Roots of Quadratic Equation

The values of the variables that are satisfying the requirements of a particular quadratic equation are known as roots. In other words, x = a is considered as one of the roots of the quadratic equation f(x), if f(a) = 0.

The real roots of the equation f(x) = 0 are termed as the x-coordinates of the points; this is the point where the curve y = f(x) intersects the x-axis.

  • It is proved that one of the roots of the quadratic equation is zero whereas the other is equal to -b/a if c = 0.

  • In case, b = c = 0 then both the roots are measured to be zero.

  • When a = c, the roots are reciprocal to each other.

 

Nature of Roots of Quadratic Equation

If the value of the discriminant = 0 i.e. b2 - 4ac = 0

In this case, the quadratic equation will have equal roots i.e. a = b = -b / 2a

If the value of discriminant < 0 i.e. b2 - 4ac < 0

In this case, the quadratic equations will have imaginary roots i.e. a = (p + iq) and b = (p - iq). Where ‘iq’ is considered as the imaginary part of a complex number. 

If the value of the discriminant (D) > 0 i.e. b2 - 4ac > 0

In this case, the quadratic equations will have real roots.

If the value of the discriminant > 0 and D is found to be a perfect square. 

In this case, the quadratic equation is going to have rational roots.

If the value of the discriminant > 0 and D is not a perfect square.

In this case, the quadratic equation is going to have irrational roots i.e. a = (p + √q) and b = (p - √q) 

If the value of the discriminant > 0 and D is found to be a perfect square.

Here, a = 1 and b & c are integers

In this case, the quadratic equation is going to have integral roots.

Quadratic Equations

Polynomial equations holding degree 2 in one variable if type f(x) = ax2 + bx + c wherever a, b, c belong to (∈) R and a ≠ 0 are known as Quadratic Equations. It's called the general form of an equation where ‘a’ is referred to as the leading coefficient, and ‘c’ is understood to be the absolute term of f(x).

The values of x that are liable for satisfying the quadratic equation are called the roots of the quadratic equation (a,b). The quadratic equation can invariably have either two roots -   real or imaginary.


Quadratic Equations and Its Roots

Roots can be defined as the values of the variables that satisfy the requirements of a given equation. x = a is said to be the roots of the quadratic equation f(x), if f(a) = 0.

The real roots of the equation f(x) = 0 can be said so because of the x-coordinates of the points; the point where the curve y = f(x) intersects the x-axis.

It's proved that one of the roots of the quadratic equation is zero whereas the opposite is equal to -b/a if c = 0.

In case, b = c = 0 then, each of the roots is measured to be zero.

Once a = c, the roots are reciprocal to one another.


Nature of the Roots of Quadratic Equations

If the value of the discriminant is equal to 0 i.e. b2 – 4ac = 0

In this case, the quadratic equation will have equal roots i.e. a = b = -b / 2a

If the value of discriminant < 0 xss=removed xss=removed> 0 i.e. b2 – 4ac > 0

In this case, the quadratic equations will have real roots.

If the worth of the discriminant > 0 and D is found to be a perfect square. 

In this case, the quadratic equation can have rational roots.

If the value of the discriminant is greater than 0 and D isn't a perfect square.

In this case, the quadratic equation can have irrational roots i.e. a = (p + √q) and b = (p – √q) 

If the value of the discriminant is greater than 0 and D is found to be a perfect square.

Here, a = 1 and b & c can be termed as integers.

In this case, the quadratic equation goes to have integral roots.

FAQs on RS Aggarwal - Class 10 Solutions for Quadratic Equations

1. How can I find the RS Aggarwal Class 10 Maths Solutions for Chapter 10, Quadratic Equations?

Vedantu provides comprehensive, step-by-step solutions for all questions in Chapter 10, Quadratic Equations, from the RS Aggarwal textbook. These solutions are crafted by subject matter experts to ensure accuracy and alignment with the CBSE curriculum. Students can access these detailed answers on the Vedantu platform to clarify doubts and master the problem-solving methods.

2. What is the step-by-step method for solving quadratic equations by factorisation in RS Aggarwal?

The factorisation method, a key technique in RS Aggarwal, involves these steps:

  • First, ensure the equation is in the standard form ax² + bx + c = 0.
  • Next, find two numbers that multiply to give 'ac' and add up to give 'b'.
  • Rewrite the middle term 'bx' using these two numbers.
  • Group the terms into two pairs and factor out the common elements from each pair.
  • Finally, factor out the common binomial expression to get the two linear factors and set each to zero to find the roots.

3. How are the solutions for problems using the quadratic formula (Sridharacharya's rule) presented?

Solutions using the quadratic formula, x = [-b ± √(b² - 4ac)] / 2a, are presented with clear, sequential steps. Each solution first identifies the values of a, b, and c from the given equation. Then, it shows the calculation of the discriminant (b² - 4ac). Finally, the values are substituted back into the formula to compute the two possible roots of the equation, simplifying the result where necessary.

4. Why is checking the discriminant (b² - 4ac) the first step before solving many RS Aggarwal problems?

Checking the discriminant (D = b² - 4ac) is a crucial first step because it reveals the nature of the roots without having to solve the entire equation. This is a strategic time-saver.

  • If D > 0, the equation has two distinct real roots.
  • If D = 0, the equation has two equal real roots.
  • If D < 0, the equation has no real roots.
Knowing this beforehand helps confirm if a real solution exists and guides you to choose the most appropriate solving method.

5. Do the RS Aggarwal solutions on Vedantu cover all exercises in Chapter 10, including the word problems?

Yes, our RS Aggarwal solutions for Class 10 Maths Chapter 10 are exhaustive. They provide detailed, step-by-step answers for every question in all exercises of the chapter, including the challenging application-based word problems. This ensures that students have a reliable resource for every problem they encounter in the textbook.

6. What are the common mistakes to avoid when solving word problems on quadratic equations from RS Aggarwal?

When tackling word problems, students often make a few common errors. The most frequent mistake is incorrectly translating the problem's language into a mathematical equation. Another common pitfall is forgetting to check if the calculated roots are valid in the context of the problem (e.g., a negative length or age is not possible). Finally, calculation errors in the discriminant or quadratic formula can lead to wrong answers. Our solutions highlight the correct way to set up and verify these problems.

7. How do the methods for 'completing the square' in RS Aggarwal solutions differ from the factorisation method, and when should I use each?

The factorisation method is fast and efficient but only works when the quadratic expression can be easily factored into integers. The method of completing the square is a more universal technique that works for all quadratic equations. You should use factorisation for simple equations where factors are obvious. For more complex equations or when asked specifically, the completing the square method is more reliable, as it systematically transforms the equation into a solvable form. It also forms the basis for deriving the quadratic formula.

8. Are the solutions for RS Aggarwal Class 10 aligned with the latest CBSE 2025-26 syllabus?

Absolutely. All RS Aggarwal solutions provided by Vedantu, including those for Class 10 Quadratic Equations, are meticulously updated and reviewed to be fully compliant with the latest CBSE syllabus for the 2025-26 academic year.
