arrange the terms in descending power hierarchy for one of the variables (x seems easiest)


(2x-3y) into (2x^3 - 9x^2 y + 17x y^2 - 12y^3)


___ 2x into 2x^3 gives x^2 ___ x^2(2x-3y) is (2x^3-3x^2 y)


___ 2x into (-6x^2 y) gives -3xy ___ -3xy(2x-3y) is (-6x^2 y + 9x y^2)


___ 2x into (8x y^2) gives 4y^2 ___ 4y^2(2x-3y) is (8x y^2 - 12y^3)


x^2 - 3xy + 4y^2</PRE>
