i think you did mistake with signs so watch it carefully
the Q should x^3+2x^2-11x+12 divided by x+4
you r going to get (x^2-2x+3) factor it (x-1)(x-3) so correct answer ((d))

If you use synthetic division, youcan quickly divide
(x^3+2x^2-11x-12) iby (x+4) getting x^2-2x-3).
This factors to (x-3)(x+1) which is answer c.

Divide the polynomial by x + 4 and then multiply the answer pairs to see which one matches your quotient. You can actually use long division to divide your polynomial by x+4.
By looking at your answer choices, I would suggest you watch your signs very carefully.

well, i believe x^3+2x^2-11x-12 is x+4 would equal...butt crack error. in other words, the answer is C.
