Foil Method

How to multiply binomials

The FOIL method is a way to multiply binomials. "FOIL" is an acronym to remember a set of rules to perform this multiplication. To FOIL you multiply together all of the following:

F: Firsts
O: Outers
I: Inners
L: Lasts

and then you add each of these products as demonstrated in the examples below.
