Question

factorise with steps

Answer 1

i hope you like these answer

Answer 2

Given⤵️

factorise :-[a²-b²]²

solution ☞

[a²-b²]²

here we used identity (a²-b²)=(a+b)(a-b)

[a²-b²]²

=[(a+b)(a-b)]²

=(a+b)²(a-b)²

Factorization using identities :-

A factorization what is solved by identities.

Example :-

(a+b)²= a²+ab+b² ---- here a example

In your problem I used the identity of a²-b².
