Question

Solve for x: −2(x − 2)2 + 5 = 0 Round your answer to the nearest hundredth.

Answer 1

-4x+8+5=0

-4x=-13

4x=13

x= 13/4

x=3.25

Answer 2

x = 3.25

Explanation:

-2(x - 2) * 2 + 5 = 0

Open parathesis

(-2x + 4) * 2 + 5 = 0

Open parenthesis again

-4x + 8 + 5 = 0

-4x + 13 = 0

-4x = -13

Divide -4 on both sides

x = 13/4

x = 3.25
