Answer:

F(x) = -3x2 -6x +3

  G(x) = -x + 2

  H(x) = 4x3 -5x2 -7x + 13

 (h - g + f) (x) = 4x3 -5x2 -7x + 13 – (-x + 2) + (-3x2 -6x +3) = 4x3 -5x2 -7x + 13 + x + 2 -3x2 -6x +3    =   4x3 -8x2 -12x + 14

 (h – f)(x) = 4x3 -5x2 -7x + 13 - (-3x2 -6x +3) = 4x3 -5x2 -7x + 13 + 3x2 -6x +3 =  4x3 -2x2 -x + 10

 (h + g + f)(x) = 4x3 -5x2 -7x + 13 + (-x + 2) + (-3x2 -6x +3) = 4x3 -8x2 -13x + 18
