Solution for (n+10)(n-11)= equation:


Simplifying
(n + 10)(n + -11) = 0

Reorder the terms:
(10 + n)(n + -11) = 0

Reorder the terms:
(10 + n)(-11 + n) = 0

Multiply (10 + n) * (-11 + n)
(10(-11 + n) + n(-11 + n)) = 0
((-11 * 10 + n * 10) + n(-11 + n)) = 0
((-110 + 10n) + n(-11 + n)) = 0
(-110 + 10n + (-11 * n + n * n)) = 0
(-110 + 10n + (-11n + n2)) = 0

Combine like terms: 10n + -11n = -1n
(-110 + -1n + n2) = 0

Solving
-110 + -1n + n2 = 0

Solving for variable 'n'.
