# The fastest and easiest way to expand the square of binomials

Visual Proof of the algebraic identity (a+b)^2=a^2 + 2ab + b^2 [Explained geometrically] |IGCSE Math

This video shows the fastest and easiest way to expand the square of any binomial. It uses the concept from the algebraic identity (a+b)^2 = a^2 + 2ab + b^2. The acronym used in this video is S-2P-S, which is an acronym introduced to guide in the fast expansion of the binomials. There are also various examples shown, with varying signs of the terms of the binomials.
