Solution for (m-5)(m+8)=0 equation:


Simplifying
(m + -5)(m + 8) = 0

Reorder the terms:
(-5 + m)(m + 8) = 0

Reorder the terms:
(-5 + m)(8 + m) = 0

Multiply (-5 + m) * (8 + m)
(-5(8 + m) + m(8 + m)) = 0
((8 * -5 + m * -5) + m(8 + m)) = 0
((-40 + -5m) + m(8 + m)) = 0
(-40 + -5m + (8 * m + m * m)) = 0
(-40 + -5m + (8m + m2)) = 0

Combine like terms: -5m + 8m = 3m
(-40 + 3m + m2) = 0

Solving
-40 + 3m + m2 = 0
