Solution for (3n+2)(2n+1)=0 equation:

Simplifying
(3n + 2)(2n + 1) = 0

Reorder the terms:
(2 + 3n)(2n + 1) = 0

Reorder the terms:
(2 + 3n)(1 + 2n) = 0

Multiply (2 + 3n) * (1 + 2n)
(2(1 + 2n) + 3n * (1 + 2n)) = 0
((1 * 2 + 2n * 2) + 3n * (1 + 2n)) = 0
((2 + 4n) + 3n * (1 + 2n)) = 0
(2 + 4n + (1 * 3n + 2n * 3n)) = 0
(2 + 4n + (3n + 6n2)) = 0

Combine like terms: 4n + 3n = 7n
