0.8888888889 + 0.6666666667m + m2 = 0

Move the constant term to the right:

Add '-0.8888888889' to each side of the equation.
0.8888888889 + 0.6666666667m + -0.8888888889 + m2 = 0 + -0.8888888889

Reorder the terms:
0.8888888889 + -0.8888888889 + 0.6666666667m + m2 = 0 + -0.8888888889

Combine like terms: 0.8888888889 + -0.8888888889 = 0.0000000000
0.0000000000 + 0.6666666667m + m2 = 0 + -0.8888888889
0.6666666667m + m2 = 0 + -0.8888888889

Combine like terms: 0 + -0.8888888889 = -0.8888888889
0.6666666667m + m2 = -0.8888888889

The m term is 0.6666666667m.  Take half its coefficient (0.3333333334).
Square it (0.1111111112) and add it to both sides.

Add '0.1111111112' to each side of the equation.
0.6666666667m + 0.1111111112 + m2 = -0.8888888889 + 0.1111111112

Reorder the terms:
0.1111111112 + 0.6666666667m + m2 = -0.8888888889 + 0.1111111112

Combine like terms: -0.8888888889 + 0.1111111112 = -0.7777777777
0.1111111112 + 0.6666666667m + m2 = -0.7777777777

Factor a perfect square on the left side:
(m + 0.3333333334)(m + 0.3333333334) = -0.7777777777

Can't calculate square root of the right side.

The solution to this equation could not be determined.
