Solution for v=x(4-2x)(9-2x) equation: 


Simplifying
v = x(4 + -2x)(9 + -2x)

Multiply (4 + -2x) * (9 + -2x)
v = x(4(9 + -2x) + -2x * (9 + -2x))
v = x((9 * 4 + -2x * 4) + -2x * (9 + -2x))
v = x((36 + -8x) + -2x * (9 + -2x))
v = x(36 + -8x + (9 * -2x + -2x * -2x))
v = x(36 + -8x + (-18x + 4x2))

Combine like terms: -8x + -18x = -26x
v = x(36 + -26x + 4x2)
v = (36 * x + -26x * x + 4x2 * x)
v = (36x + -26x2 + 4x3)

Solving
v = 36x + -26x2 + 4x3

Solving for variable 'v'.

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

Simplifying
v = 36x + -26x2 + 4x3
