1. Factoring Take a trinomial and break it into two binomials.
Ex: x2 + 7x + 6 = (x + 6)(x + 1)

2. Notes X2 + 3x + 2 ( + )( + ) X2 - 3x - 2 ( + )( - )

3. factoring
x2 - 4x - 21
X2 – 9x + 20
X2 + 6x + 8 X2 + 4x + 4

4. Factoring
X2 – x - 8 X2 – 8x + 15
X2 + 9x + 14
X2 + 3x + 5

5. Factoring
X2 - 2x - 24
X2 + 4x + 3
X2 + 8x + 7
X2 + 2x - 3

6. Factor
x2 – 5x + 4
X2 – 4x + 4
X2 – 8x + 7
X2 – 7x + 12

7. Solve by Factoring X2 – 11x + 28 = 0 X2 – 3x – 10 = 0

8. Solve by factoring X2 + 4x + 3 = 0 X2 – 5x + 4 = 0 X2 + 5x – 6 = 0

9. Homework (factor the trinomial and solve)
X2 + 6x + 5 x2 + 8x – 9 X2 + 5x – 3 x2 – x – 20 x2 + 8x + 16 x2 – 3x – 18 M2 – 7m – 30 w2 + 13w + 36 B2 + 3b – 40 x2 + 7x + 10 X2 + 5x – 14 x2 + 6x + 9 X2 + 16x + 15 x2 – 20x + 100
