Simplifying m2 + -3mn + -28n2 = 0 Reorder the terms: -3mn + m2 + -28n2 = 0 Solving -3mn + m2 + -28n2 = 0 Solving for variable 'm'. Factor a trinomial. (m + -7n)(m + 4n) = 0Subproblem 1
Set the factor '(m + -7n)' equal to zero and attempt to solve: Simplifying m + -7n = 0 Solving m + -7n = 0 Move all terms containing m to the left, all other terms to the right. Add '7n' to each side of the equation. m + -7n + 7n = 0 + 7n Combine like terms: -7n + 7n = 0 m + 0 = 0 + 7n m = 0 + 7n Remove the zero: m = 7n Simplifying m = 7nSubproblem 2
Set the factor '(m + 4n)' equal to zero and attempt to solve: Simplifying m + 4n = 0 Solving m + 4n = 0 Move all terms containing m to the left, all other terms to the right. Add '-4n' to each side of the equation. m + 4n + -4n = 0 + -4n Combine like terms: 4n + -4n = 0 m + 0 = 0 + -4n m = 0 + -4n Remove the zero: m = -4n Simplifying m = -4nSolution
m = {7n, -4n}
