Perfect Square Formula
Perfect Square Formula is basically Multiplying Monomials and Polynomials but you're taught how to do it more easily. The trick is (a+b)^2 = a^2 + 2ab + b^2, (a-b)^2 = a^2 - 2ab + b^2.
If you once again come across a question like (x+1)(x-1), then I once again repeat, the answer will always be something like x2 - 1^2!!! There is never a third term!!!
