SPECIAL PRODUCTS OF POLYNOMIALS Section 7.3

What You Will Learn 1.Use the square of a binomial pattern. 2.Use the sum and difference pattern. 3.Use special product patterns to solve real-life problems.

Using the Square of a Binomial Pattern

Find each product.

Find each product.(You Try)

Bellwork

In Exercises 11–12, write a polynomial that represents the area of the square.

Using the Sum and Difference Pattern

Find each product using the Sum and Difference Pattern. a. (t + 5)(t − 5) b. (3x + y)(3x − y)

Find each product using the Sum and Difference Pattern(You Try) 1. (x + 10)(x − 10) 2. (2x + 1)(2x − 1) 3. (x + 3y)(x −3y)
