Simplifying 3m2 = 15 + -12m Solving 3m2 = 15 + -12m Solving for variable 'm'. Reorder the terms: -15 + 12m + 3m2 = 15 + -12m + -15 + 12m Reorder the terms: -15 + 12m + 3m2 = 15 + -15 + -12m + 12m Combine like terms: 15 + -15 = 0 -15 + 12m + 3m2 = 0 + -12m + 12m -15 + 12m + 3m2 = -12m + 12m Combine like terms: -12m + 12m = 0 -15 + 12m + 3m2 = 0 Factor out the Greatest Common Factor (GCF), '3'. 3(-5 + 4m + m2) = 0 Factor a trinomial. 3((-5 + -1m)(1 + -1m)) = 0 Ignore the factor 3.Subproblem 1
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 = -5Subproblem 2
Set the factor '(1 + -1m)' equal to zero and attempt to solve: Simplifying 1 + -1m = 0 Solving 1 + -1m = 0 Move all terms containing m to the left, all other terms to the right. Add '-1' to each side of the equation. 1 + -1 + -1m = 0 + -1 Combine like terms: 1 + -1 = 0 0 + -1m = 0 + -1 -1m = 0 + -1 Combine like terms: 0 + -1 = -1 -1m = -1 Divide each side by '-1'. m = 1 Simplifying m = 1Solution
m = {-5, 1}
