      simplify 7x2  y2- 3xy + 4x2y2 - 8xy
      hmmmm
       14  y2 - 3xy + 4x2y2 - 8xy
      combine -3xy and -8xy  = -11xy
      14 y2 - 11xy  + 4x2y2
      I see 16y2 and -11xy and 4x 
      This is too hard for me.  Sorry

        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" ??????
