If the function h(x) is defined by h(x) = 2x? - 7x-12 then which of the following values of x solves the equation h(x) = 10?
(1) x = -2
(3) x = 48
(2) x = 5
(4) x = 118

x=-2 solves the equation h(x)=10.

Step-by-step explanation:

Given the function

Putting in the function

switch both sides

add 12 to both sides

Divide both sides by 2

Rewriting in the form x²+2ax+a²
