Question

Find the solutions to the equation below.

Check all that apply.

4x^2 - 4x - 2 = 0

A. x = -1/2

B. x = 3/2

C. x = 1/2

D. x = -2

E. x = 3

F. x = 2

Answer 1

A and B.

Explanation:

4x^2 - 4x - 3 = 0

4x^2 + 2x - 6x - 3 = 0

2x(2x + 1) - 3(2x + 1) = 0

(2x - 3)(2x + 1) = 0

x = 3/2, -1/2.
