Question

identities of factorization?

Answer 1

Factorization using Identities :There are some identities and using that the factorization is much easier.

A number of expressions to be factorized are of the form or can be put into the form : a 2 + 2ab + b 2 , a 2 – 2ab + b 2 , a 2 – b 2 and x 2 + (a + b) + ab. These expressions can be easily factorized using Identities I, II, III and IV

In this section we will learn Factorization using Identities one by one.

1) a2 + 2ab + b2 = (a + b)2 

2) a2 – 2ab + b2 = (a – b)2 

3) a2 – b2 = (a + b) (a – b) 

4) x2 + (a + b) x + ab = (x + a) (x + b)

Answer 2

Hey buddy here is your answer !!

(a+b)^2 = a^2+2ab+b^2
(a-b)^2 =a^2 - 2ab +b^2
a^2 - b^2 = (a-b) (a+b)

Hope these formulas will help you to factorise !!!
