For this case we have the following polynomial:
 (4x + 5) (- 3x-1)
 Rewriting we have:
 -12x ^ 2 - 4x - 15x - 5
 -12x ^ 2 - 19x - 5
 The equivalent polynomials for this case are given by:
 (-16x ^ 2 + 10x - 3) + (4x ^ 2 - 29x - 2)
 2 (x - 1) - 3 (4x ^ 2 + 7x + 1)
 (2x ^ 2 - 11x - 9) - (14x ^ 2 + 8x - 4)
 Answer:
 (-16x ^ 2 + 10x - 3) + (4x ^ 2 - 29x - 2)
 2 (x - 1) - 3 (4x ^ 2 + 7x + 1)
 (2x ^ 2 - 11x - 9) - (14x ^ 2 + 8x - 4)
answers would be A D C
