Simplifying 2m(4m + -7) + 5 = 0 Reorder the terms: 2m(-7 + 4m) + 5 = 0 (-7 * 2m + 4m * 2m) + 5 = 0 (-14m + 8m2) + 5 = 0 Reorder the terms: 5 + -14m + 8m2 = 0 Solving 5 + -14m + 8m2 = 0 Solving for variable 'm'. Factor a trinomial. (1 + -2m)(5 + -4m) = 0Subproblem 1
Set the factor '(1 + -2m)' equal to zero and attempt to solve: Simplifying 1 + -2m = 0 Solving 1 + -2m = 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 + -2m = 0 + -1 Combine like terms: 1 + -1 = 0 0 + -2m = 0 + -1 -2m = 0 + -1 Combine like terms: 0 + -1 = -1 -2m = -1 Divide each side by '-2'. m = 0.5 Simplifying m = 0.5Subproblem 2
Set the factor '(5 + -4m)' equal to zero and attempt to solve: Simplifying 5 + -4m = 0 Solving 5 + -4m = 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 + -4m = 0 + -5 Combine like terms: 5 + -5 = 0 0 + -4m = 0 + -5 -4m = 0 + -5 Combine like terms: 0 + -5 = -5 -4m = -5 Divide each side by '-4'. m = 1.25 Simplifying m = 1.25Solution
m = {0.5, 1.25}
