n(n+1)(n-1)=720

Solution for n(n+1)(n-1)=720 equation:

Simplifying
n(n + 1)(n + -1) = 720

Reorder the terms:
n(1 + n)(n + -1) = 720

Reorder the terms:
n(1 + n)(-1 + n) = 720

Multiply (1 + n) * (-1 + n)
n(1(-1 + n) + n(-1 + n)) = 720
n((-1 * 1 + n * 1) + n(-1 + n)) = 720
n((-1 + 1n) + n(-1 + n)) = 720
n(-1 + 1n + (-1 * n + n * n)) = 720
n(-1 + 1n + (-1n + n2)) = 720

Combine like terms: 1n + -1n = 0
n(-1 + 0 + n2) = 720
n(-1 + n2) = 720
(-1 * n + n2 * n) = 720
(-1n + n3) = 720

Solving
-1n + n3 = 720

Solving for variable 'n'.

Reorder the terms:
-720 + -1n + n3 = 720 + -720

Combine like terms: 720 + -720 = 0
-720 + -1n + n3 = 0
