Solution for V(x)=(20-2x)*(20-2x)*(x) equation: 



(V)=(20-2V)(20-2V)(V)

We move all terms to the left:

(V)-((20-2V)(20-2V)(V))=0

We add all the numbers together, and all the variables

V-((-2V+20)(-2V+20)V)=0

We multiply parentheses ..

-((+4V^2-40V-40V+400)V)+V=0



We calculate terms in parentheses: -((+4V^2-40V-40V+400)V), so:

(+4V^2-40V-40V+400)V

We multiply parentheses

4V^3-40V^2-40V^2+400V

We do not support eVpression: V^3
