(m-8)(m+17)=0

Solution for (m-8)(m+17)=0 equation:

Simplifying
(m + -8)(m + 17) = 0

Reorder the terms:
(-8 + m)(m + 17) = 0

Reorder the terms:
(-8 + m)(17 + m) = 0

Multiply (-8 + m) * (17 + m)
(-8(17 + m) + m(17 + m)) = 0
((17 * -8 + m * -8) + m(17 + m)) = 0
((-136 + -8m) + m(17 + m)) = 0
(-136 + -8m + (17 * m + m * m)) = 0
(-136 + -8m + (17m + m2)) = 0

Combine like terms: -8m + 17m = 9m
(-136 + 9m + m2) = 0

Solving
-136 + 9m + m2 = 0

Solving for variable 'm'.
