Solution for V=x(9-2x)(7-2x) equation: 


Simplifying
V = x(9 + -2x)(7 + -2x)

Multiply (9 + -2x) * (7 + -2x)
V = x(9(7 + -2x) + -2x * (7 + -2x))
V = x((7 * 9 + -2x * 9) + -2x * (7 + -2x))
V = x((63 + -18x) + -2x * (7 + -2x))
V = x(63 + -18x + (7 * -2x + -2x * -2x))
V = x(63 + -18x + (-14x + 4x2))

Combine like terms: -18x + -14x = -32x
