(n-6)(n+4)=0

Solution for (n-6)(n+4)=0 equation:

Simplifying
(n + -6)(n + 4) = 0

Reorder the terms:
(-6 + n)(n + 4) = 0

Reorder the terms:
(-6 + n)(4 + n) = 0

Multiply (-6 + n) * (4 + n)
(-6(4 + n) + n(4 + n)) = 0
((4 * -6 + n * -6) + n(4 + n)) = 0
((-24 + -6n) + n(4 + n)) = 0
(-24 + -6n + (4 * n + n * n)) = 0
(-24 + -6n + (4n + n2)) = 0

Combine like terms: -6n + 4n = -2n
(-24 + -2n + n2) = 0

Solving
-24 + -2n + n2 = 0

Solving for variable 'n'.
