Answer:

{-5, 2}

Explanation:


2x^(2) + 2x + 12 = 3x^(2) -x + 2 move everything to the right side


-2x^(2) -2x-12=-2x^(2) -2x-12 add line 1 and 2 to get the below equation


0 = x^(2) -3x -10 find multiples of -10 that add to give you -3

to get -10 we have to have (+)(-)

{-5, 2}

Explanation:


2x^2+2x+12=3x^2-x+2\\2x+12=x^2-x+2\\x^2-3x-10=0\\(x-5)(x+2)=0\\x=5, -2

The correct answer is choice D. Hope this helps!
