Answer:
-9xy² - 6x²y + 5x
Step-by-step explanation:
The additive inverse of a polynomial is simply defined as the same polynomial but the difference is that the signs attached to each of the terms will change. This means that positive sign will change to negative while negative sign will change to positive.
Now, we are given the polynomial;
9xy² + 6x²y - 5x
Thus, from earlier description, additive inverse of this polynomial is;
-9xy² - 6x²y + 5x
