    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

    is it
    a. 11x3y3
    b. 11x4y4 - 11x2y2
    c. 11x2y2 - 11xy
    d. 11x2y2 + 11xy

    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" ??????
