Question

a²-b²-a-b factorise.. Solve this problem

Answer 1

here is your answer frnd....

Factorise a2 - b2 - a - b
a2 - b2 - a - b = [(a - b)(a + b)] - (a + b) = (a + b)(a - b - 1).

Therefore, factors of a2 - b2 - a - b are (a + b)(a - b - 1).

thnks....
hope its help uuuu

Answer 2

The factors of given expression is $(a+b)\ \text{and}\ (a-b-1)$.

Step-by-step explanation:

We need to factorize a²-b²-a-b.

For this use formula $a^2-b^2=(a-b)(a+b)$

$a^2-b^2-a-b =[(a-b)(a+b) -(a+b)]\\\\a^2-b^2-a-b =(a+b)[(a-b)-1]\\\\a^2-b^2-a-b =(a+b)(a-b-1)$

So, the factors of given expression is $(a+b)\ \text{and}\ (a-b-1)$.
