(3n+11)(n+1)=0

Solution for (3n+11)(n+1)=0 equation:

Simplifying
(3n + 11)(n + 1) = 0

Reorder the terms:
(11 + 3n)(n + 1) = 0

Reorder the terms:
(11 + 3n)(1 + n) = 0

Multiply (11 + 3n) * (1 + n)
(11(1 + n) + 3n * (1 + n)) = 0
((1 * 11 + n * 11) + 3n * (1 + n)) = 0
((11 + 11n) + 3n * (1 + n)) = 0
(11 + 11n + (1 * 3n + n * 3n)) = 0
(11 + 11n + (3n + 3n2)) = 0

Combine like terms: 11n + 3n = 14n
