1. Bellwork: 2/13/18 Find each product.
1. (x + 2)(x + 7) 2. (x – 11)(x + 5)
3. (x – 10)2
Factor each polynomial.
4. x2 + 12x x2 + 2x – 63
6. x2 – 10x x2 – 16x + 32

2. Solving Quadratic Equations
We will...
solve quadratic equations by factoring.

3. Solve by graphing: 1)
x = 0
2) -x2 + 12x - 36 = 0
3) 2x2 = 3x2 - 2x - 8
4) -2x2 - 6 = 0

5. Use the Zero Product Property to solve the equation. 
Check your answer.
(x – 7)(x + 2) = 0
(5x + 4)(2x – 3) = 0
(x)(3x + 4) = 0
(x – 2)(x) = 0

6. Solve the quadratic equation by factoring. Check your 
answer.
x2 – 6x + 8 = 0
x2 + 4x = 21
–2x2 = 20x + 50
x2 – 12x + 36 = 0

7. Solve the quadratic equation by factoring. Check your 
answer.
x2 – 6x + 9 = 0
x2 + 4x = 5
30x = –9x2 – 25
3x2 – 4x + 1 = 0

8. 3) x2- 3x = 10 5) -3x2 = 18x + 27 2) x2 - 8x - 9 = 0 4) x2 + 10x = -16
