The solution to the quadratic equation 5 + 3x - 2x2

The solution to the quadratic equation 5 + 3x - 2x2 = 0 is

A.

(52, 1)

B.

(5, 3)

C.

-(52, -1)

D.

(52, -1)

View answer & explanation

Correct answer is D

5 + 3x - 2x2 = 0, (x + 1)(5 - 2x) (expand to check)

(x + 1)(5 - 2x) = 0

when x = 1 = 0, x = -1

when 5 - 2x = 0, x = 52 - 1
