Reorder the terms for easier multiplication:
x(-1 + x)(9 + x) = 72

Multiply (-1 + x) * (9 + x)
x(-1(9 + x) + x(9 + x)) = 72
x((9 * -1 + x * -1) + x(9 + x)) = 72
x((-9 + -1x) + x(9 + x)) = 72
x(-9 + -1x + (9 * x + x * x)) = 72
x(-9 + -1x + (9x + x2)) = 72

Combine like terms: -1x + 9x = 8x
x(-9 + 8x + x2) = 72
(-9 * x + 8x * x + x2 * x) = 72
(-9x + 8x2 + x3) = 72

Solving
-9x + 8x2 + x3 = 72

Solving for variable 'x'.
