(2x-3y)^4
=(2x)^4-4*(2x)^3*(3y)+6*(2x)^2*(3y)^2-4*(2x)*(3y)^3+(3y)^4
=16x^4-96x^3*y+216x^2*y^2-216x*y^3+81y^4

(2x-3y)^4
2x-3y
2x-3y
--------------
4x^2-12xy+9y^2
2x-3y
------------------
8x^3-24x^2y+18xy^2-12x^2y+36xy^2-27y^3
8x^3-36x^2y+54xy^2-27y^3
2x-3y
----------------------------------
16x^4-72x^3y+108x^2y^2-54xy^3-24x^3y+108x^2y^2-162xy^3+81y^4
16x^4-126x^3y+216x^2y^2-216xy^3+81y^4 ans.
