Question

use identity and factorise (x-2) (x+3)​

Answer 1

Answer:

Factorization by using identities will help us to factorize an algebraic expression easily.

The following identities are:

(i) (a + b)2 = a2 + 2ab +b2,

(ii) (a - b)2 = a2 - 2ab + b2 and

(iii) a2 – b2 = (a + b)(a – b).

Now we will use these identities to factorize the given algebraic expressions.
