fxD=x^{3}-2
The equation is in standard form.
\frac{fxD}{fx}=\frac{x^{3}-2}{fx}
Divide both sides by fx.
D=\frac{x^{3}-2}{fx}
Dividing by fx undoes the multiplication by fx.
Dxf=x^{3}-2
The equation is in standard form.
\frac{Dxf}{Dx}=\frac{x^{3}-2}{Dx}
Divide both sides by Dx.
f=\frac{x^{3}-2}{Dx}
Dividing by Dx undoes the multiplication by Dx.
