Answer 1

Answer: 3x^3 + 6x^2 - 17x - 21

Step-by-step explanation:

To simplify the equation,

1. you first want to multiply the "-" to (-7x^3 + x^2 + 5x +10)
2. This would make the 2nd half of the equation: 7x^3 - x^2 - 5x - 10
3. Now combine like terms. -4x^3 + 7x^3 | 7x^2 - x^2 | -12x - 5x | -11 - 10|
4. You get 3x^3 + 6x^2 - 17x - 21
