Answer:
The answer is
9xy2-6x2y+5x3
The additive inverse of a polynomial is the same polynomial with the signs of the terms changed.
The additive inverse of the given polynomial is (9xy² - 6x²y + 5x³).
The additive inverse of a polynomial can be obtained by multiplying the polynomial with (- 1).
The given polynomial is (- 9xy² + 6x²y - 5x³)
Therefore, the additive inverse of the given polynomial is
= - (- 9xy² + 6x²y - 5x³)
= (9xy² - 6x²y + 5x³)
