Kita sederhanan dulu
y ( x +2)³ = (xy + 2y)³
              = (xy + 2y) (xy + 2y)(xy + 2y)
              = (x²+y² +  2xy²  + 2xy² + 4y²) ( xy + 2y )
              = (x²+y² +  4xy²  + 4y² ) ( xy + 2y )
              = x³y³ + 2x³y³ + 4x²y³ + 8xy³ + 4xy³ + 8y³
              = y³x³ +8x²y³ + 12xy³ + 8y³
sekarang kerjakan obsennya
$begin{align} y(x+2) ^{3} : 8xy : y & = (xy+2y) ^{3} times frac{y}{8xy}\ &= (xy +2) (xy+2) (xy+2)times frac{y}{8xy} \ &= y ^{3} x^{3} +8x^{2} y^{3} + 12xy^{3} + 8y^{3}times frac{1}{8x} \ &= frac{ y ^{3} x^{3} +8x^{2} y^{3} + 12xy^{3} + 8y^{3}}{8x} \ &= error.... end{align}
