__Questions:__**Factor each expression.**

- x + 9x + 20
- x - 5x + 6
- x + 5x - 6
- x - 3x - 28
- x + 8x + 12
- x + 2x - 3
- x - 7x + 12
- x + 7x - 8
- x + 3x - 10
- x + 10x + 21

Tip:

Note that for the problems in this lesson, the coefficient for the squared term is 1. The factoring process changes slightly when that coefficient is a different number.

answer:

- (x + 4)(x + 5)
- (x - 2)(x - 3)
- (x + 6)(x - 1)
- (x + 4)(x - 7)
- (x + 2)(x + 6)
- (x + 3)(x - 1)
- (x - 3)(x - 4)
- (x + 8)(x - 1)
- (x -2)(x + 5)
- (x + 3)(x + 7)
