If we were to factor it what 2 numbers multiply to 32 and addd to 12 8 and 4 (x+8)(x+4) both signs are positive since all signs in equation are positive
so D is the correct answe
we can use eliminateion also to find the answer
we see that the sign of x^2 and 12x and 32 are both positive, so the signs of the factors also must be positive (can't be B or C) then, we need to find what 2 numbers multiply to get 32 and add to 12 if we picked 2 (for A), then 2 times 16=32, but 2+16≠12 4 times 8=32 and 4+8=12 so it must be D
