Divide each side by '12'.
0.4166666667 + 1.5m + m2 = 0

Move the constant term to the right:

Add '-0.4166666667' to each side of the equation.
0.4166666667 + 1.5m + -0.4166666667 + m2 = 0 + -0.4166666667

Reorder the terms:
0.4166666667 + -0.4166666667 + 1.5m + m2 = 0 + -0.4166666667

Combine like terms: 0.4166666667 + -0.4166666667 = 0.0000000000
0.0000000000 + 1.5m + m2 = 0 + -0.4166666667
1.5m + m2 = 0 + -0.4166666667

Combine like terms: 0 + -0.4166666667 = -0.4166666667
1.5m + m2 = -0.4166666667

The m term is 1.5m.  Take half its coefficient (0.75).
Square it (0.5625) and add it to both sides.

Add '0.5625' to each side of the equation.
1.5m + 0.5625 + m2 = -0.4166666667 + 0.5625
