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