4(3-m)-5m(m-3)=

Solution for 4(3-m)-5m(m-3)= equation:

Simplifying
4(3 + -1m) + -5m(m + -3) = 0
(3 * 4 + -1m * 4) + -5m(m + -3) = 0
(12 + -4m) + -5m(m + -3) = 0

Reorder the terms:
12 + -4m + -5m(-3 + m) = 0
12 + -4m + (-3 * -5m + m * -5m) = 0
12 + -4m + (15m + -5m2) = 0

Combine like terms: -4m + 15m = 11m
12 + 11m + -5m2 = 0

Solving
12 + 11m + -5m2 = 0

Solving for variable 'm'.
