Choose any 3 of the following 4 equations to solve. You must be sure to. Use a DIFFERENT method for each one, using the three methods in this list: a) Quadratic Formula

b) Completing the Square

c) Factoring/Zero Product Property

Write on the line next to the problem which method you used.

Show all work, round any irrational solutions to the nearest hundredth.

1) 4x^2 − 4x = 3

2) x^2 − 6x − 20 = 0

3) 5x^2 + 2x − 3 = 3x − 2

4) x^2 + 4x − 21 = 0
