PLZZZZZZZZZZ HELP MEEEEEEEE

Answer 1

Answer:

D

Step-by-step 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!

Answer 2

Answer:

{-5, 2}

Step-by-step 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}
