Class 10

NCERT solutions for class 10 maths chapter 4 ex 4.2 Quadratic Equations explains how to solve quadratic equations using factorization, concept of roots and zero of  polynomials. students will be able to find the roots by the splitting method of quadratic equation which is, factoring the quadratic equation into two linear factors and that each factor is equal to zero.

This exercise consists of six questions where students have to figure out quadratic equations using a factorization method. The solutions for this exercise are available as downloadable PDF format. Class 10 maths chapter 4 ex 4.2 NCERT solutions deal with a significant topic. You can download the free PDF and practice these questions of ex 4.2.

Topics Covered in Exercise 4.2 Class 10 Mathematics Questions

students need to have a thorough understanding of the topics used in ex 4.2 and here we have provided the important topics of this exercise.


Solution of a Quadratic Equation by Factorisation

  1. Solution of a Quadratic Equation by Factorisation - Class 10 maths ex 4.2 is based on the concept of factorisation, which is the process of dividing the middle term in order to solve quadratic Equations by Factorisation. To achieve this, the terms must be arranged as follows: ax2 + bx + c = 0.

So, it is necessary to identify the product of the first and last expressions. Then, we split the middle term into two terms, the product of which should be the same as the first and last expressions. Finally, the terms must be grouped in order to factorize the expression. The roots of the condition, as well as the zeros in the polynomial, are the same.

Frequently Asked Questions

Question 1.  What is the splitting of the middle term in chapter 4 ex 4.2 ?

Answer 1. The middle term of a quadratic expression cannot be separated; instead, it must be rewrite as the sum of the two terms or the difference of two terms. This shows that the middle term must be divided into two parts in the sense of the sum or difference of the terms.

Question 2. What is the main topic to be covered in class 10 maths ex 4.2 in chapter 4 ?

Answer 2. Chapter 4 focuses on the formation of quadratic equations. However, ex 4.2 mainly focuses on the factorization method and how to use it to solve the quadratic equation. Roots and Zero of a polynomial are also included in this exercise. These concepts may seem tough at first, but they are easy to understand if you practice them regularly before the exam.
