Question

(Apex!) Select the two values of x that are roots of this equation 3x-5=-2x^2

A. x= 2
B. x= -5/2
C. x= -1/3
D. x= 1

Answer 1

B and D

Explanation:

Write as a quadratic

-2x² - 3x + 5 = 0

Factor

-2x² - 5x + 2x + 5 = 0

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

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

To make the equation 0, x is either 1 or -5/2.
