1. ## solve equation

Solve for x
(3x + 5)(2x - 6) = 0

2. If the product of factors equals zero, then at least one factor equals 0.

You have 2 factors. Set them equal to zero and solve for x.

3. set each factor equal to 0 ...

3x + 5 = 0
x = -5/3

2x - 6 = 0
x = 3

5. Another problem!

Solve for x

2x - 9 < 9x + 4

&

-4x - 6 > 7x - 14
