Solution for (m+8)(m-15)=0 equation:


Simplifying
(m + 8)(m + -15) = 0

Reorder the terms:
(8 + m)(m + -15) = 0

Reorder the terms:
(8 + m)(-15 + m) = 0

Multiply (8 + m) * (-15 + m)
(8(-15 + m) + m(-15 + m)) = 0
((-15 * 8 + m * 8) + m(-15 + m)) = 0
((-120 + 8m) + m(-15 + m)) = 0
(-120 + 8m + (-15 * m + m * m)) = 0
(-120 + 8m + (-15m + m2)) = 0

Combine like terms: 8m + -15m = -7m
(-120 + -7m + m2) = 0

Solving
-120 + -7m + m2 = 0

Solving for variable 'm'.
