      Multiplying by One or More Terms

      Multiplying algebraic expressions is much like multiplying numbers, but the introduction of variables makes the process just a bit more interesting. Products involving variables call on the rules of exponents. And, because of the commutative property of addition and multiplication, arrangements and rearrangements of terms and factors can make the process simpler.

      When multiplying by one or more terms, you deal with the following in this chapter:

       Distributing terms with one or more factors over two or more terms — multiplication over sums and differences

       Distributing division over sums and differences and dividing each term in the parentheses

       Distributing binomials over binomials or trinomials and then combining like terms

       Multiplying binomials using FOIL: First, Outer, Inner, Last

       Using Pascal’s triangle to find powers of binomials

       Finding products of binomials times trinomials that create sums and differences of cubes

      With all the distributing and multiplying, don’t overlook the following:

       Applying the rules of exponents to all terms when distributing variables over several terms

       Changing the sign of each term when distributing a negative factor over several terms

       Combining the outer and inner terms correctly when applying FOIL

       Starting with the zero power when assigning powers of the second term to the pattern in Pascal’s triangle

      311–315 Distribute the number over the terms in the parentheses.
