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

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

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

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

Reorder the terms:
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 + 8xX + x2X) = 72

Solving
-9X + 8xX + x2X = 72

Solving for variable 'X'.

Move all terms containing X to the left, all other terms to the right.
