Understanding Binomial Squaring and FOIL Method

The video tutorial explains how to square a binomial by multiplying it by itself. It guides viewers through setting up the binomial, applying the FOIL method, and managing signs and coefficients. The tutorial emphasizes the importance of combining like terms and suggests using Desmos for accuracy.

What does it mean to square a binomial?

• Add the binomial to itself

• Multiply the binomial by itself

• Divide the binomial by itself

• Subtract the binomial from itself
