Description

The term FOIL is a mnemonic for the standard method of multiplying two binomials. The method is therefore also known as the FOIL method. The word FOIL is an acronym for the four English terms of the product:

First (The "first" terms of each binomial are multiplied together)
Outer (The "outer" terms are multiplied - i.e. the first term of the first binomial and the second term of the second)
Inner (The "inner" terms are multiplied - second term of the first binomial and first term of the second)
Last (The "last" terms of each binomial are multiplied)

The general form is

\((a+b)(c+d)=a·c\;+\;a·d\;+\;b·c\;+\;b·d\)
