 * In this section you will learn to find the squares of sums and differences and to find the product of a sum and a difference. Some pairs of binomials have products that follow a specific pattern. One pattern is the //square of a sum, (a+b) (a+b) or (a+b)2. Pages: 458-463.//

//**Key Concepts:** Square of a Sum- (a+b) x (a+b) = (a) x (a) + 2ab + (b) x (b) Square of Difference- (a-b) x (a-b) = (a) x (a) - 2ab + (b) x (b) Product of a Sum and a Difference (a-b) x (a+b) = (a) x (a) - (b) x (b)

1. Rewrite terms 2. Use foil 3. Combine like terms
 * Steps:**

1. (y + 4)² (y + 4)² (y + 4) (y + 4) y² + 8y + 16
 * Example:**

2. (2g + 5)² (2g + 5)² (2g + 5) (2g +5) 4g² + 20g +25
