Solution for 0=(n+1)(n-8) equation: 


Simplifying
0 = (n + 1)(n + -8)

Reorder the terms:
0 = (1 + n)(n + -8)

Reorder the terms:
0 = (1 + n)(-8 + n)

Multiply (1 + n) * (-8 + n)
0 = (1(-8 + n) + n(-8 + n))
0 = ((-8 * 1 + n * 1) + n(-8 + n))
0 = ((-8 + 1n) + n(-8 + n))
0 = (-8 + 1n + (-8 * n + n * n))
0 = (-8 + 1n + (-8n + n2))

Combine like terms: 1n + -8n = -7n
0 = (-8 + -7n + n2)

Solving
0 = -8 + -7n + n2

Solving for variable 'n'.

Combine like terms: 0 + 8 = 8
8 + 7n + -1n2 = -8 + -7n + n2 + 8 + 7n + -1n2

Reorder the terms:
8 + 7n + -1n2 = -8 + 8 + -7n + 7n + n2 + -1n2

Combine like terms: -8 + 8 = 0
8 + 7n + -1n2 = 0 + -7n + 7n + n2 + -1n2
8 + 7n + -1n2 = -7n + 7n + n2 + -1n2

Combine like terms: -7n + 7n = 0
8 + 7n + -1n2 = 0 + n2 + -1n2
8 + 7n + -1n2 = n2 + -1n2

Combine like terms: n2 + -1n2 = 0
8 + 7n + -1n2 = 0

Factor a trinomial.
(8 + -1n)(1 + n) = 0
