Simplifying 21 + 22m + m2 = 0 Solving 21 + 22m + m2 = 0 Solving for variable 'm'. Factor a trinomial. (21 + m)(1 + m) = 0Subproblem 1
Set the factor '(21 + m)' equal to zero and attempt to solve: Simplifying 21 + m = 0 Solving 21 + m = 0 Move all terms containing m to the left, all other terms to the right. Add '-21' to each side of the equation. 21 + -21 + m = 0 + -21 Combine like terms: 21 + -21 = 0 0 + m = 0 + -21 m = 0 + -21 Combine like terms: 0 + -21 = -21 m = -21 Simplifying m = -21Subproblem 2
Set the factor '(1 + m)' equal to zero and attempt to solve: Simplifying 1 + m = 0 Solving 1 + m = 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 + m = 0 + -1 Combine like terms: 1 + -1 = 0 0 + m = 0 + -1 m = 0 + -1 Combine like terms: 0 + -1 = -1 m = -1 Simplifying m = -1Solution
m = {-21, -1}
