(n+1)(n+2)=110

Solution for (n+1)(n+2)=110 equation:

Simplifying
(n + 1)(n + 2) = 110

Reorder the terms:
(1 + n)(n + 2) = 110

Reorder the terms:
(1 + n)(2 + n) = 110

Multiply (1 + n) * (2 + n)
(1(2 + n) + n(2 + n)) = 110
((2 * 1 + n * 1) + n(2 + n)) = 110
((2 + 1n) + n(2 + n)) = 110
(2 + 1n + (2 * n + n * n)) = 110
(2 + 1n + (2n + n2)) = 110

Combine like terms: 1n + 2n = 3n
(2 + 3n + n2) = 110

Solving
2 + 3n + n2 = 110

Solving for variable 'n'.

Reorder the terms:
2 + -110 + 3n + n2 = 110 + -110

Combine like terms: 2 + -110 = -108
-108 + 3n + n2 = 110 + -110

Combine like terms: 110 + -110 = 0
-108 + 3n + n2 = 0

Add '-9' to each side of the equation.
9 + -9 + -1n = 0 + -9

Combine like terms: 9 + -9 = 0
0 + -1n = 0 + -9
-1n = 0 + -9

Combine like terms: 0 + -9 = -9
-1n = -9

Divide each side by '-1'.
n = 9

Simplifying
n = 9
Solution
n = {-12, 9}
