                -x4y
                -x4y - x3y2                (x+y) *-x3y
               --------------
                       x3y2
                       x3y2+ x2y3          (x+y) *x2y2
                     ---------------
                           - x2y3
                           - x2y3- xy4     (x+y)*-xy3     
                          -------------
