(n + 3)(n + -2) = 36

Reorder the terms:
(3 + n)(n + -2) = 36

Reorder the terms:
(3 + n)(-2 + n) = 36

Multiply (3 + n) * (-2 + n)
(3(-2 + n) + n(-2 + n)) = 36
((-2 * 3 + n * 3) + n(-2 + n)) = 36
((-6 + 3n) + n(-2 + n)) = 36
(-6 + 3n + (-2 * n + n * n)) = 36
(-6 + 3n + (-2n + n2)) = 36

Combine like terms: 3n + -2n = 1n
(-6 + 1n + n2) = 36

Solving
-6 + 1n + n2 = 36
