Question

Which of the following is a solution to the equation 4x2+4x−3=0?

-1.5


-0.5


1


3

Answer 1

-1.5

Explanation:

4x² + 4x - 3 = 0

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

2x + 3 = 0 or 2x - 1 = 0

x = -3/2 or x = 1/2

Answer: -1.5

Answer 2

if you mean 4 times 2 + 4x - 3 = 0 then the answer is:

x = -5/4 (-1.25)

If you mean 4x2 + 4x - 3 = 0 then:

x = 0.5 or -1.5
