Solution for v=(6-2x)(15-2x)(x) equation: 


Simplifying
v = (6 + -2x)(15 + -2x)(x)

Reorder the terms for easier multiplication:
v = x(6 + -2x)(15 + -2x)

Multiply (6 + -2x) * (15 + -2x)
v = x(6(15 + -2x) + -2x * (15 + -2x))
v = x((15 * 6 + -2x * 6) + -2x * (15 + -2x))
v = x((90 + -12x) + -2x * (15 + -2x))
v = x(90 + -12x + (15 * -2x + -2x * -2x))
v = x(90 + -12x + (-30x + 4x2))

Combine like terms: -12x + -30x = -42x
v = x(90 + -42x + 4x2)
v = (90 * x + -42x * x + 4x2 * x)
v = (90x + -42x2 + 4x3)

Solving
v = 90x + -42x2 + 4x3

Solving for variable 'v'.

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

Simplifying
v = 90x + -42x2 + 4x3
