Solution for (m-3n)(m-3n)= equation:


Simplifying
(m + -3n)(m + -3n) = 0

Multiply (m + -3n) * (m + -3n)
(m(m + -3n) + -3n * (m + -3n)) = 0
((m * m + -3n * m) + -3n * (m + -3n)) = 0

Reorder the terms:
((-3mn + m2) + -3n * (m + -3n)) = 0
((-3mn + m2) + -3n * (m + -3n)) = 0
(-3mn + m2 + (m * -3n + -3n * -3n)) = 0
(-3mn + m2 + (-3mn + 9n2)) = 0

Reorder the terms:
(-3mn + -3mn + m2 + 9n2) = 0

Combine like terms: -3mn + -3mn = -6mn
(-6mn + m2 + 9n2) = 0

Solving
-6mn + m2 + 9n2 = 0

Solving for variable 'm'.

Factor a trinomial.
(m + -3n)(m + -3n) = 0

Subproblem 1

Set the factor '(m + -3n)' equal to zero and attempt to solve: Simplifying m + -3n = 0 Solving m + -3n = 0 Move all terms containing m to the left, all other terms to the right. Add '3n' to each side of the equation. m + -3n + 3n = 0 + 3n Combine like terms: -3n + 3n = 0 m + 0 = 0 + 3n m = 0 + 3n Remove the zero: m = 3n Simplifying m = 3n

Subproblem 2

Set the factor '(m + -3n)' equal to zero and attempt to solve: Simplifying m + -3n = 0 Solving m + -3n = 0 Move all terms containing m to the left, all other terms to the right. Add '3n' to each side of the equation. m + -3n + 3n = 0 + 3n Combine like terms: -3n + 3n = 0 m + 0 = 0 + 3n m = 0 + 3n Remove the zero: m = 3n Simplifying m = 3n

Solution

m = {3n, 3n}
