Solving for variable 'm'.

Begin completing the square.  Divide all terms by
3 the coefficient of the squared term: 

Divide each side by '3'.
-4 + 1.333333333m + m2 = 0

Move the constant term to the right:

Add '4' to each side of the equation.
-4 + 1.333333333m + 4 + m2 = 0 + 4

Reorder the terms:
-4 + 4 + 1.333333333m + m2 = 0 + 4

Combine like terms: -4 + 4 = 0
0 + 1.333333333m + m2 = 0 + 4
1.333333333m + m2 = 0 + 4

Combine like terms: 0 + 4 = 4
1.333333333m + m2 = 4

The m term is 1.333333333m.  Take half its coefficient (0.6666666665).
Square it (0.4444444442) and add it to both sides.

Add '0.4444444442' to each side of the equation.
1.333333333m + 0.4444444442 + m2 = 4 + 0.4444444442

Reorder the terms:
