Solution for V(x)=(20-2x)*(10-2x)*x equation: 



(V)=(20-2V)(10-2V)*V

We move all terms to the left:

(V)-((20-2V)(10-2V)*V)=0

We add all the numbers together, and all the variables

V-((-2V+20)(-2V+10)*V)=0

We multiply parentheses ..

-((+4V^2-20V-40V+200)*V)+V=0



We calculate terms in parentheses: -((+4V^2-20V-40V+200)*V), so:

(+4V^2-20V-40V+200)*V

We multiply parentheses

4V^3-20V^2-40V^2+200V

We do not support eVpression: V^3
