Solution for (n-1)(n+1)n=210 equation:


Simplifying
(n + -1)(n + 1) * n = 210

Reorder the terms:
(-1 + n)(n + 1) * n = 210

Reorder the terms:
(-1 + n)(1 + n) * n = 210

Reorder the terms for easier multiplication:
n(-1 + n)(1 + n) = 210

Multiply (-1 + n) * (1 + n)
n(-1(1 + n) + n(1 + n)) = 210
n((1 * -1 + n * -1) + n(1 + n)) = 210
n((-1 + -1n) + n(1 + n)) = 210
n(-1 + -1n + (1 * n + n * n)) = 210
n(-1 + -1n + (1n + n2)) = 210

Combine like terms: -1n + 1n = 0
n(-1 + 0 + n2) = 210
n(-1 + n2) = 210
(-1 * n + n2 * n) = 210
(-1n + n3) = 210

Solving
-1n + n3 = 210

Solving for variable 'n'.
