Answer 1

`4x^(3) +8x^(2) - 23x+4`

Explanation:

Assuming that x has no definite value, first, lets substitute the equation
`2(A-B)` with the values given to us.

`2(2x^(3) -7x+1)-(-8x^(2) +9x-2)`

Then, solve. (Remember, whenever a negative is in front of parentheses, we would use distributive property and treat it like a -1)

`4x^(3) -14x+2 + 8x^(2) - 9x+2` Distributive Property

`4x^(3) +8x^(2) - 23x+4` Simplify

Therefore, our answer is
`4x^(3) +8x^(2) - 23x+4`.
