Given Equation is (a + 2b)^2 - a^2
⇒ a^2 + 4b^2 + 4ab - a^2
⇒ 4b^2 + 4ab
⇒ 4b(a + b).
Therefore, Factorization of (a + 2b)^2 - a^2 = 4b(a + b).
Hope this helps!
BabuDubu:
can you please explain how 4ab came?
We know that (a + b)^2 = a^2 + 2ab + b^2.
Given:
(a + 2b)^2
= > (a)^2 + (2b)^2 + 2(a)(2b)
= > a^2 + 4b^2 + 4ab
Given:
(a + 2b)^2
= > (a)^2 + (2b)^2 + 2(a)(2b)
= > a^2 + 4b^2 + 4ab
thanx
