Solution for (7-2x)(8-2x)(x)=v equation: 


Simplifying
(7 + -2x)(8 + -2x)(x) = v

Reorder the terms for easier multiplication:
x(7 + -2x)(8 + -2x) = v

Multiply (7 + -2x) * (8 + -2x)
x(7(8 + -2x) + -2x * (8 + -2x)) = v
x((8 * 7 + -2x * 7) + -2x * (8 + -2x)) = v
x((56 + -14x) + -2x * (8 + -2x)) = v
x(56 + -14x + (8 * -2x + -2x * -2x)) = v
x(56 + -14x + (-16x + 4x2)) = v

Combine like terms: -14x + -16x = -30x
x(56 + -30x + 4x2) = v
(56 * x + -30x * x + 4x2 * x) = v
(56x + -30x2 + 4x3) = v

Solving
56x + -30x2 + 4x3 = v

Solving for variable 'x'.

Reorder the terms:
-1v + 56x + -30x2 + 4x3 = v + -1v

Combine like terms: v + -1v = 0
-1v + 56x + -30x2 + 4x3 = 0
