(n-8)(n+3)=0

Solution for (n-8)(n+3)=0 equation:

Simplifying
(n + -8)(n + 3) = 0

Reorder the terms:
(-8 + n)(n + 3) = 0

Reorder the terms:
(-8 + n)(3 + n) = 0

Multiply (-8 + n) * (3 + n)
(-8(3 + n) + n(3 + n)) = 0
((3 * -8 + n * -8) + n(3 + n)) = 0
((-24 + -8n) + n(3 + n)) = 0
(-24 + -8n + (3 * n + n * n)) = 0
(-24 + -8n + (3n + n2)) = 0

Combine like terms: -8n + 3n = -5n
(-24 + -5n + n2) = 0

Solving
-24 + -5n + n2 = 0

Solving for variable 'n'.
