Solution for m(4-m)(5+m)=0 equation: 


Simplifying
m(4 + -1m)(5 + m) = 0

Multiply (4 + -1m) * (5 + m)
m(4(5 + m) + -1m * (5 + m)) = 0
m((5 * 4 + m * 4) + -1m * (5 + m)) = 0
m((20 + 4m) + -1m * (5 + m)) = 0
m(20 + 4m + (5 * -1m + m * -1m)) = 0
m(20 + 4m + (-5m + -1m2)) = 0

Combine like terms: 4m + -5m = -1m
m(20 + -1m + -1m2) = 0
(20 * m + -1m * m + -1m2 * m) = 0
(20m + -1m2 + -1m3) = 0

Solving
20m + -1m2 + -1m3 = 0

Solving for variable 'm'.

Factor out the Greatest Common Factor (GCF), 'm'.
m(20 + -1m + -1m2) = 0
