Solution for V(x)=(21-2x)(29.7-2x)(x) equation: 



(V)=(21-2V)(29.7-2V)(V)

We move all terms to the left:

(V)-((21-2V)(29.7-2V)(V))=0

We add all the numbers together, and all the variables

V-((-2V+21)(-2V+29.7)V)=0

We multiply parentheses ..

-((+4V^2-59.4V-42V+623.7)V)+V=0



We calculate terms in parentheses: -((+4V^2-59.4V-42V+623.7)V), so:

(+4V^2-59.4V-42V+623.7)V

We multiply parentheses

4V^3-59V^2-42V^2+623.7V

We do not support eVpression: V^3
