To multiply any two binomials, use FOIL.

First: Multiply the first term of the first binomial times the first term of the second binomial.

Outside: Multiply the first term of the first binomial times the second term fo the second binomial.

Inside: Multiply the second term of the first binomial times the first term of the second binomial.

Last: Multiply the second term of the first binomial times the second term of the second binomial.

Faster process when multiplying conjugates. Binomial Conjugates differ only by the sign between the two terms. and are conjugates. The result of multiplying conjugates is the difference of the first term squared and the second term squared, namely:
