(x)(x+9)(x-1)=72

Solution for (x)(x+9)(x-1)=72 equation:

Simplifying
(x)(x + 9)(x + -1) = 72

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

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

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

Combine like terms: 9x + -1x = 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'.

Reorder the terms:
-72 + -9x + 8x2 + x3 = 72 + -72

Combine like terms: 72 + -72 = 0
-72 + -9x + 8x2 + x3 = 0
