1. 2.

 1. The product of the sum and difference of two terms.  2. The square of a binomial sum.  3. The square of a binomial difference.

3. 4.

 Multiply each term of one of the polynomials by each term of the other, and then add all the monomial products.  It may be helpful to line up the common terms vertically.

5.

6.

 To cube a binomial, write the binomial times. FOIL two binomials and then multiply the resulting trinomial by the remaining binomial. three
