Solution for 0=4m^2-20m equation:


Simplifying
0 = 4m2 + -20m

Reorder the terms:
0 = -20m + 4m2

Solving
0 = -20m + 4m2

Solving for variable 'm'.
Remove the zero:
20m + -4m2 = -20m + 4m2 + 20m + -4m2

Reorder the terms:
20m + -4m2 = -20m + 20m + 4m2 + -4m2

Combine like terms: -20m + 20m = 0
20m + -4m2 = 0 + 4m2 + -4m2
20m + -4m2 = 4m2 + -4m2

Combine like terms: 4m2 + -4m2 = 0
20m + -4m2 = 0

Factor out the Greatest Common Factor (GCF), '4m'.
4m(5 + -1m) = 0

Ignore the factor 4.

Subproblem 1

Set the factor 'm' equal to zero and attempt to solve: Simplifying m = 0 Solving m = 0 Move all terms containing m to the left, all other terms to the right. Simplifying m = 0

Subproblem 2

Set the factor '(5 + -1m)' equal to zero and attempt to solve: Simplifying 5 + -1m = 0 Solving 5 + -1m = 0 Move all terms containing m to the left, all other terms to the right. Add '-5' to each side of the equation. 5 + -5 + -1m = 0 + -5 Combine like terms: 5 + -5 = 0 0 + -1m = 0 + -5 -1m = 0 + -5 Combine like terms: 0 + -5 = -5 -1m = -5 Divide each side by '-1'. m = 5 Simplifying m = 5

Solution

m = {0, 5}
