Topics Covered in Exercise 2.3 Class 9 Mathematics Questions

Ex 2.3 class 9 maths solutions includes factorisation of polynomials, which is an essential topic to build a solid foundation of algebra for the students.

1. Factorisation of Polynomials - Factorisation of polynomials is a procedure to show the polynomials as the product of two or more polynomials. For example, The polynomial x2-3x-10 can be factorised as (x-5) (x+2).
2. Factor Theorem - If p(x) is a polynomial of degree n 1 and a is any real number, then (i) x – a is a factor of p(x), if p(a) = 0, and 

(ii) p(a) = 0, if x – a is a factor of p(x).

Method to find the factorisation of polynomial:

• By Spliting the middle term

               x2+bx+c=x2+(p+q)+pqx2+bx+c

                                    = (x + p)(x + q)

This means that we need to split the middle term in a way so that the sum of the two terms  is equal to 'b' and the product is equal to 'c'.
