Solution for (40-2x)(30-2x)(x)=v equation: 


Simplifying
(40 + -2x)(30 + -2x)(x) = v

Reorder the terms for easier multiplication:
x(40 + -2x)(30 + -2x) = v

Multiply (40 + -2x) * (30 + -2x)
x(40(30 + -2x) + -2x * (30 + -2x)) = v
x((30 * 40 + -2x * 40) + -2x * (30 + -2x)) = v
x((1200 + -80x) + -2x * (30 + -2x)) = v
x(1200 + -80x + (30 * -2x + -2x * -2x)) = v
x(1200 + -80x + (-60x + 4x2)) = v

Combine like terms: -80x + -60x = -140x
x(1200 + -140x + 4x2) = v
(1200 * x + -140x * x + 4x2 * x) = v
(1200x + -140x2 + 4x3) = v

Solving
1200x + -140x2 + 4x3 = v

Solving for variable 'x'.

Reorder the terms:
-1v + 1200x + -140x2 + 4x3 = v + -1v

Combine like terms: v + -1v = 0
-1v + 1200x + -140x2 + 4x3 = 0

The solution to this equation could not be determined.
