What are the steps in squaring a binomials?

Answer 1

Squaring a binomial is just a mater of taking the binomial times itself, for example

(a+b)2=(a+b)*(a+b)

Here you apply FOIL technique, meaning: First, Outer, Inner and Last -- see below

(a*a)+(a*b)+(b*a)+(b*b)

Observing that (a*b)=(b*a) in alegbra the above equation can be rewritten as:

a2+2ab+b2
