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



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

We move all terms to the left:

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

We add all the numbers together, and all the variables

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

We multiply parentheses ..

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



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

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

We multiply parentheses

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

We do not support eVpression: V^3
