For a binomial times a binomial, use FOIL. FOIL stands for First, Outside, Inside, Last.

First:

(the first terms of each)

Outside:

(the first term of the first binomial and the last term of the second binomial)

Inside:

(the last term of the first binomial and the first term of the second binomial)

Last:

(the last terms of each)

Add the terms:

Collect like terms:

There is nothing particularly sacred about the order in which the operations are performed. It is just that Outside, Last, Inside, First = OLIF doesn't spell anything that a student would be likely to remember, and neither does FLIO, LFOI, etc.
