Solution for 768=(x-4)(x)(x-16) equation:


Simplifying
768 = (x + -4)(x)(x + -16)

Reorder the terms:
768 = (-4 + x)(x)(x + -16)

Reorder the terms:
768 = (-4 + x) * x(-16 + x)

Reorder the terms for easier multiplication:
768 = x(-4 + x)(-16 + x)

Multiply (-4 + x) * (-16 + x)
768 = x(-4(-16 + x) + x(-16 + x))
768 = x((-16 * -4 + x * -4) + x(-16 + x))
768 = x((64 + -4x) + x(-16 + x))
768 = x(64 + -4x + (-16 * x + x * x))
768 = x(64 + -4x + (-16x + x2))

Combine like terms: -4x + -16x = -20x
768 = x(64 + -20x + x2)
768 = (64 * x + -20x * x + x2 * x)
768 = (64x + -20x2 + x3)

Solving
768 = 64x + -20x2 + x3

Solving for variable 'x'.

Reorder the terms:
768 + -64x + 20x2 + -1x3 = 64x + -64x + -20x2 + 20x2 + x3 + -1x3
