12-37.
  1. Solve each equation below for the given variable. Check your solution by verifying that your solution makes the original equation true. Homework Help ✎

    1. (15u − 6) = 14u

    2. (5 − x)(3x + 8) = 0

    3. 2(k − 5)2 = 32

    4. 2p2 + 7p − 9 = 0

Distribute before simplifying.

10u − 4 = 14u
− 4 = 4u
u = − 1

Use the Zero Product Property.

Divide by 2 first and be sure to find two solutions.

k = 1 or 9

Use the Quadratic Formula.

p = −4.5 or 1
