Overview

When you multiply two binomials that have similar terms in each then rather than FOIL you can use formulae that are derived from FOIL. These are called special product formulae. Note that you don't have to use them, but many people find them useful. For instance, you could just FOIL (x+y)(x+y) and simplify rather than using the binomial squared formula to expand.
