m^2-2mn-15n^2=

Solution for m^2-2mn-15n^2= equation:

Simplifying
m2 + -2mn + -15n2 = 0

Reorder the terms:
-2mn + m2 + -15n2 = 0

Solving
-2mn + m2 + -15n2 = 0

Solving for variable 'm'.

Factor a trinomial.
(m + -5n)(m + 3n) = 0

Subproblem 1
Set the factor '(m + -5n)' equal to zero and attempt to solve:

Simplifying
m + -5n = 0

Solving
m + -5n = 0

Move all terms containing m to the left, all other terms to the right.

Add '5n' to each side of the equation.
m + -5n + 5n = 0 + 5n

Combine like terms: -5n + 5n = 0
m + 0 = 0 + 5n
m = 0 + 5n
Remove the zero:
m = 5n

Simplifying
m = 5n
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 = {5n, -3n}
