Answer:


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.
