Simplifying
(3x)(x + -8)(x + -8) = 135

Remove parenthesis around (3x)
3x(x + -8)(x + -8) = 135

Reorder the terms:
3x(-8 + x)(x + -8) = 135

Reorder the terms:
3x(-8 + x)(-8 + x) = 135

Multiply (-8 + x) * (-8 + x)
3x(-8(-8 + x) + x(-8 + x)) = 135
3x((-8 * -8 + x * -8) + x(-8 + x)) = 135
3x((64 + -8x) + x(-8 + x)) = 135
3x(64 + -8x + (-8 * x + x * x)) = 135
3x(64 + -8x + (-8x + x2)) = 135

Combine like terms: -8x + -8x = -16x
3x(64 + -16x + x2) = 135
(64 * 3x + -16x * 3x + x2 * 3x) = 135
