Answer 2

Answer:

To get from 10x^3 - 4x^2 + 10x to 14x^3 + x^2 - x, we need to add 4x^3 + x^2 - 11x.

This is because when we add 4x^3 to 10x^3, we get 14x^3, and when we add x^2 to -4x^2, we get -3x^2. Finally, when we add -11x to 10x, we get -x.

So,

10x^3 - 4x^2 + 10x + (4x^3 + x^2 - 11x) = 14x^3 + x^2 - x.

Hence, we need to add 4x^3 + x^2 - 11x to 10x^3 - 4x^2 + 10x to get 14x^3 + x^2 - x.
