Square binomials. Square of a Binomial The square of a binomial is a trinomial consisting of For x and y, the following are true. Notice that in the square of a sum, all of the terms are positive. In the square of a difference, the middle term is negative. A common error when squaring a binomial is to forget the middle term of the product.

Objective 2 Find the product of the sum and difference of two terms. Copyright © 2012, 2008, 2004 Pearson Education, Inc. Slide 5. 6 -7
Find the product of the sum and difference of two terms. In binomial products of the form (x + y)(x − y), one binomial is the sum of two terms and the other is the difference of the same two terms. Consider (x + 2)(x − 2). Product of the Sum and Difference of Two Terms The product rules of this section are essential as we continue to chapters 6 and 7. Remember and practice them.
