Answer:
The answer would be -5x²+3x+9
Step-by-step explanation:
This is because to get to 0, you'll add the inverse to the original equation.
Example of an inverse equation:
4x+1 (Original) ----> -4x-1 (Inverse)
When an inverse equation is added to the original equation, it equals 0. This is due to the like terms canceling each other out.
To get the inverse equation, make all of the positive terms negative, and all of the negative terms positive.
