Simplifying 2m2 = -1m + 28 Reorder the terms: 2m2 = 28 + -1m Solving 2m2 = 28 + -1m Solving for variable 'm'. Reorder the terms: -28 + m + 2m2 = 28 + -1m + -28 + m Reorder the terms: -28 + m + 2m2 = 28 + -28 + -1m + m Combine like terms: 28 + -28 = 0 -28 + m + 2m2 = 0 + -1m + m -28 + m + 2m2 = -1m + m Combine like terms: -1m + m = 0 -28 + m + 2m2 = 0 Factor a trinomial. (-4 + -1m)(7 + -2m) = 0Subproblem 1
Set the factor '(-4 + -1m)' equal to zero and attempt to solve: Simplifying -4 + -1m = 0 Solving -4 + -1m = 0 Move all terms containing m to the left, all other terms to the right. Add '4' to each side of the equation. -4 + 4 + -1m = 0 + 4 Combine like terms: -4 + 4 = 0 0 + -1m = 0 + 4 -1m = 0 + 4 Combine like terms: 0 + 4 = 4 -1m = 4 Divide each side by '-1'. m = -4 Simplifying m = -4Subproblem 2
Set the factor '(7 + -2m)' equal to zero and attempt to solve: Simplifying 7 + -2m = 0 Solving 7 + -2m = 0 Move all terms containing m to the left, all other terms to the right. Add '-7' to each side of the equation. 7 + -7 + -2m = 0 + -7 Combine like terms: 7 + -7 = 0 0 + -2m = 0 + -7 -2m = 0 + -7 Combine like terms: 0 + -7 = -7 -2m = -7 Divide each side by '-2'. m = 3.5 Simplifying m = 3.5Solution
m = {-4, 3.5}
