(n+3)(3n+2)=0

Solution for (n+3)(3n+2)=0 equation:

Simplifying
(n + 3)(3n + 2) = 0

Reorder the terms:
(3 + n)(3n + 2) = 0

Reorder the terms:
(3 + n)(2 + 3n) = 0

Multiply (3 + n) * (2 + 3n)
(3(2 + 3n) + n(2 + 3n)) = 0
((2 * 3 + 3n * 3) + n(2 + 3n)) = 0
((6 + 9n) + n(2 + 3n)) = 0
(6 + 9n + (2 * n + 3n * n)) = 0
(6 + 9n + (2n + 3n2)) = 0

Combine like terms: 9n + 2n = 11n
(6 + 11n + 3n2) = 0

Solving
6 + 11n + 3n2 = 0
