Question

factorize solve the problem​

Answer 1

Step-by-step explanation:

Given that:

$(a+b)^3-a-b$

To find factors of given polynomial, first of all take -1 common from the last two terms

$(a+b)^3-(a+b)$

Now take (a+b) common from both terms

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

Now apply the identity

$x^2-y^2=(x+y)(x-y)$

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

$(a+b)[(a+b+1)(a+b-1)]$

thus factors of

$\bold{(a+b)^3-a-b}\\=\bold{(a+b)(a+b+1)(a+b-1)}$

Hope it helps you.
