(n+2)(3n-5)=

Solution for (n+2)(3n-5)= equation:

Simplifying
(n + 2)(3n + -5) = 0

Reorder the terms:
(2 + n)(3n + -5) = 0

Reorder the terms:
(2 + n)(-5 + 3n) = 0

Multiply (2 + n) * (-5 + 3n)
(2(-5 + 3n) + n(-5 + 3n)) = 0
((-5 * 2 + 3n * 2) + n(-5 + 3n)) = 0
((-10 + 6n) + n(-5 + 3n)) = 0
(-10 + 6n + (-5 * n + 3n * n)) = 0
(-10 + 6n + (-5n + 3n2)) = 0

Combine like terms: 6n + -5n = 1n
(-10 + 1n + 3n2) = 0

Solving
-10 + 1n + 3n2 = 0

Solving for variable 'n'.
