You have negative 3xy and negative 8xy. That has to be negative 11xy (-11xy)
That is really the only thing I'm confident is correct.
I can't be sure of the line, actually.
7x2y2 = 7x2y(squared)?
4x2y2 = 4x2y(squared)?
That would be 11x2y(squared) - 11xy. That could end up being 2y(squared) - y???? That could then be "y" ??????
