  1. MULTIPLYING POLYNOMIALS

  2. 3x + 5 2x Consider the triangle below with polynomial side lengths of 2x, 3x + 5, and 2(x – 1). The perimeter of the triangle is 24. Use polynomial addition to solve for x. Then determine the length of each side of the triangle. 2(x -1)

  3. The glass portion of a sliding glass door has a ratio of height to width of 2:1. The framework adds 10 inches to the width and 12 inches to the height. a. Write a polynomial expression that represents the total area of the window, including the framework. B. Find the area when x = 9, and when x =12.

  4. 7 ft 13 ft 10 ft Mrs. Moore wants to take care of some home improvements during fall break. The first job she plans to tackle his her back yard. She wants to lay sod and she wants to plant a flower garden. She has decided to do the work herself; she doesn’t need professionals. Below is a diagram of her landscaping plans. The green represents grass, and the brown is her garden. How many square feet of sod will she need? 30 ft

  5. X X² X Today, we will use algebra tiles to represent polynomial multiplication. When we used algebra tiles to add polynomials, we discovered that the big square represents x² because it is a square with side lengths of x.

  6. 2x(4x – 2)
