Subproblem 1
Set the factor '(-3 + -1m2)' equal to zero and attempt to solve:

Simplifying
-3 + -1m2 = 0

Solving
-3 + -1m2 = 0

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

Add '3' to each side of the equation.
-3 + 3 + -1m2 = 0 + 3

Combine like terms: -3 + 3 = 0
0 + -1m2 = 0 + 3
-1m2 = 0 + 3

Combine like terms: 0 + 3 = 3
-1m2 = 3

Divide each side by '-1'.
m2 = -3

Simplifying
m2 = -3

This subproblem is being ignored because a solution could not be determined.
Subproblem 2
Set the factor '(6 + -1m2)' equal to zero and attempt to solve:

Simplifying
6 + -1m2 = 0

Solving
6 + -1m2 = 0

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

Add '-6' to each side of the equation.
6 + -6 + -1m2 = 0 + -6

Combine like terms: 6 + -6 = 0
0 + -1m2 = 0 + -6
-1m2 = 0 + -6

Combine like terms: 0 + -6 = -6
-1m2 = -6

Divide each side by '-1'.
m2 = 6
