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

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

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

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

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

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

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

Solving
-24 + 2n + n2 = 0

Solving for variable 'n'.
