Solution for V=(10-2x)(7-2x)x equation: 


Simplifying
V = (10 + -2x)(7 + -2x) * x

Reorder the terms for easier multiplication:
V = x(10 + -2x)(7 + -2x)

Multiply (10 + -2x) * (7 + -2x)
V = x(10(7 + -2x) + -2x * (7 + -2x))
V = x((7 * 10 + -2x * 10) + -2x * (7 + -2x))
V = x((70 + -20x) + -2x * (7 + -2x))
V = x(70 + -20x + (7 * -2x + -2x * -2x))
V = x(70 + -20x + (-14x + 4x2))

Combine like terms: -20x + -14x = -34x
V = x(70 + -34x + 4x2)
V = (70 * x + -34x * x + 4x2 * x)
V = (70x + -34x2 + 4x3)

Solving
V = 70x + -34x2 + 4x3

Solving for variable 'V'.
