X(x-1)(x+1)=210

Solution for X(x-1)(x+1)=210 equation:

Simplifying
X(x + -1)(x + 1) = 210

Reorder the terms:
X(-1 + x)(x + 1) = 210

Reorder the terms:
X(-1 + x)(1 + x) = 210

Multiply (-1 + x) * (1 + x)
X(-1(1 + x) + x(1 + x)) = 210
X((1 * -1 + x * -1) + x(1 + x)) = 210
X((-1 + -1x) + x(1 + x)) = 210
X(-1 + -1x + (1 * x + x * x)) = 210
X(-1 + -1x + (1x + x2)) = 210

Combine like terms: -1x + 1x = 0
X(-1 + 0 + x2) = 210
X(-1 + x2) = 210
(-1 * X + x2 * X) = 210
(-1X + x2X) = 210

Solving
-1X + x2X = 210

Solving for variable 'X'.

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