1. Objective: To multiply binomials using Area Model

2. Draw a rectangle. Split it into four. Fill in the following. 3 5 4 2 What is the area of the rectangle? 6 2012 10 12 + 20 + 6 + 10 = 48 square units

3. 2x 6 3x 1 What is the area of this rectangle? 2x 18x6x 2 6 6x 2 + 18x + 2x + 6 = 6x 2 + 20x + 6 (2x + 6)(3x + 1) = 6x 2 + 20x + 6

4. 4x -3 5x 2 What is the area of this rectangle? 8x -15x20x 2 -6 20x 2 - 15x + 8x - 6 = 20x 2 - 7x - 6 (4x - 3)(5x + 2) =20x 2 - 7x - 6

5. Practice! Multiply the following. 1. (5x + 1)(2x + 4) = 2. (x + 7)(x – 3) = 3. (4x – 2)(x + 1) = 4. (3x + 2)(x + 2) = 5. (x + 5)(x + 5) = 6. (x – 5)(x – 5) = 7. (x + 5)(x - 5) = 8. (x + 1)(2x + 9) = 9. (x + 5)(x – 8) = 10. (3x + 2)(x + 7) = 11. (-5x + 2)(x + 3) = 12. (x + 2)(x + 2) = 13. (x – 2)(x – 2) = 14. (x + 2)(x - 2) = You have 5 minutes to copy this slide!
