9x³-3x²-x-10

b)(3x³+4x²-5x-1) - (5x³-8x²-6x+4)

3x³+4x²-5x-1-5x³+8x²+6x-4

-2x³+12x²+x-5

c)(5x³-8x²-6x+4) + (3x³+4x²-5x-1)

5x³-8x²-6x+4+3x³+4x²-5x-1

8x³-4x²-11x+3

d)(5x³-8x²-6x+4) - (6x³-7x²+4x-9)

5x³-8x²-6x+4-6x³+7x²-4x+9

-x³-x²-8x+13

e)(6x³-7x²+4x-9) + (3x³+4x²-5x-1) + (5x³-8x²-6x+4)

6x³-7x²+4x-9+3x³+4x²-5x-1+5x³-8x²-6x+4

9x³-3x²-x-10+5x³-8x²-6x+4

14x³-11x²-7x-6
