The additive inverse of the polynomial is +7y²-x²y+3xy+7x².

What is Additive inverse?

The additive inverse can be defined as when we add a number to some number and get result as zero.

Given polynomial:

-7y²+x²y-3xy-7x²

As, the value of additive inverse is same as of the number but the sign of the additive inverse is opposite.

So,

=  +7y²-x²y+3xy+7x²

Check:

-7y²+x²y-3xy-7x² + 7y²-x²y+3xy+7x²

= -7y²+  7y² +x²y -x²y -3xy +3xy -7x² +7x²

=0

Hence, the additive inverse of the polynomial is +7y²-x²y+3xy+7x².
