Divide each side by '3'.
-1.666666667 + m + m2 = 0

Move the constant term to the right:

Add '1.666666667' to each side of the equation.
-1.666666667 + m + 1.666666667 + m2 = 0 + 1.666666667

Reorder the terms:
-1.666666667 + 1.666666667 + m + m2 = 0 + 1.666666667

Combine like terms: -1.666666667 + 1.666666667 = 0.000000000
0.000000000 + m + m2 = 0 + 1.666666667
m + m2 = 0 + 1.666666667

Combine like terms: 0 + 1.666666667 = 1.666666667
m + m2 = 1.666666667

The m term is m.  Take half its coefficient (0.5).
Square it (0.25) and add it to both sides.

Add '0.25' to each side of the equation.
 + 0.25 + m2 = 1.666666667 + 0.25

Combine like terms:  + 0.25 = 1.25
1.25 + m2 = 1.666666667 + 0.25

Combine like terms: 1.666666667 + 0.25 = 1.916666667
1.25 + m2 = 1.916666667
