9-17.
  1. Solve the following quadratic equations by factoring and using the Zero Product Property. Be sure to check your solutions. Homework Help ✎

    1. x2 − 13x + 42 = 0

    2. 0 = 3x2 + 10x − 8

    3. 2x2 − 10x = 0

    4. 4x2 + 8x − 60 = 0

Draw a generic rectangle and diamond.

Factor.

(x − 6) (x − 7) = 0

One solution is x = 6.
Make sure you find the other solution.

0 = (3x − 2) (? + ?)

Notice that each term is a multiple of 4.

x = 3 or x = −5

There are only 2 terms, so factor using the GCF.
