Why a-b Square is equal to.. Let's see the explanation with visual proof of algebraic identity (a-b) Square...In this Tutorial, you will learn why (a-b) whole square is equal to a square plus b square - 2ab . This is an algebraic identity with two variables and holds true for any value of a and b.
i.e. (a-b)^2 = a^2 - 2ab + b^2

We have used this formula in so many questions. Have you ever wondered how this formula is derived and how this holds true ?

You can expand this using Binomial theorem. But one of the simplest way to prove this formula and check how this algebraic identity holds true is, Prove by geometrically.

Let’s see how this formula holds true geometrically.
