Simplifying -21m2 + -20m = 0 Reorder the terms: -20m + -21m2 = 0 Solving -20m + -21m2 = 0 Solving for variable 'm'. Factor out the Greatest Common Factor (GCF), '-1m'. -1m(20 + 21m) = 0 Ignore the factor -1.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 = 0Subproblem 2
Set the factor '(20 + 21m)' equal to zero and attempt to solve: Simplifying 20 + 21m = 0 Solving 20 + 21m = 0 Move all terms containing m to the left, all other terms to the right. Add '-20' to each side of the equation. 20 + -20 + 21m = 0 + -20 Combine like terms: 20 + -20 = 0 0 + 21m = 0 + -20 21m = 0 + -20 Combine like terms: 0 + -20 = -20 21m = -20 Divide each side by '21'. m = -0.9523809524 Simplifying m = -0.9523809524Solution
m = {0, -0.9523809524}
