So far, all of the expressions have been monomials. The same rule applies to binomials.

 

You can use these rules to simplify the following:

 

 

m5_eqn447.eps

 

 

m5_eqn448.eps

 

This process can be used to simplify another binomial product. Read the following or go to Multiplying Binomial Radicals.

Did You Know?


A special case of multiplication that you may recall from your Grade 10 math course is the multiplication of binomial conjugates. Binomial conjugates are two binomials that are otherwise identical; but one is the addition of the terms, and the other is the subtraction of the terms. When these are multiplied together, there is a difference of squares.
