Simplifying 7m2 = -21m Solving 7m2 = -21m Solving for variable 'm'. Reorder the terms: 21m + 7m2 = -21m + 21m Combine like terms: -21m + 21m = 0 21m + 7m2 = 0 Factor out the Greatest Common Factor (GCF), '7m'. 7m(3 + m) = 0 Ignore the factor 7.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 '(3 + m)' equal to zero and attempt to solve: Simplifying 3 + m = 0 Solving 3 + m = 0 Move all terms containing m to the left, all other terms to the right. Add '-3' to each side of the equation. 3 + -3 + m = 0 + -3 Combine like terms: 3 + -3 = 0 0 + m = 0 + -3 m = 0 + -3 Combine like terms: 0 + -3 = -3 m = -3 Simplifying m = -3Solution
m = {0, -3}
