Solution for V=(30-2x)(20-3x)x equation: 


Simplifying
V = (30 + -2x)(20 + -3x) * x

Reorder the terms for easier multiplication:
V = x(30 + -2x)(20 + -3x)

Multiply (30 + -2x) * (20 + -3x)
V = x(30(20 + -3x) + -2x * (20 + -3x))
V = x((20 * 30 + -3x * 30) + -2x * (20 + -3x))
V = x((600 + -90x) + -2x * (20 + -3x))
V = x(600 + -90x + (20 * -2x + -3x * -2x))
V = x(600 + -90x + (-40x + 6x2))

Combine like terms: -90x + -40x = -130x
V = x(600 + -130x + 6x2)
V = (600 * x + -130x * x + 6x2 * x)
V = (600x + -130x2 + 6x3)

Solving
V = 600x + -130x2 + 6x3

Solving for variable 'V'.

Move all terms containing V to the left, all other terms to the right.
