What is the additive inverse of the polynomial? negative 7 y squared plus x squared y minus 3 x y minus 7 x squared

The additive inverse is found by changing the sign of every term so the polynomial and its inverse add to zero. Thus, the inverse of −7y² + x²y − 3xy − 7x² is 7y² − x²y + 3xy + 7x², which is choice A.
