Factorization of Perfect Square
Content
To factorize a perfect square we will learn how to factor different types of algebraic expressions using the following identities.
(i) a2 + 2ab + b2 = (a + b)2 = (a + b) (a + b)
(ii) a2 – 2ab + b2 = (a – b)2 = (a – b) (a – b)
Examples;
1. Factorize the perfect square completely:
(i) 4x2 + 9y2 + 12xy
