Add '-0.2857142857' to each side of the equation.
0.2857142857 + -0.2857142857m + -0.2857142857 + m2 = 0 + -0.2857142857

Reorder the terms:
0.2857142857 + -0.2857142857 + -0.2857142857m + m2 = 0 + -0.2857142857

Combine like terms: 0.2857142857 + -0.2857142857 = 0.0000000000
0.0000000000 + -0.2857142857m + m2 = 0 + -0.2857142857
-0.2857142857m + m2 = 0 + -0.2857142857

Combine like terms: 0 + -0.2857142857 = -0.2857142857
-0.2857142857m + m2 = -0.2857142857

The m term is -0.2857142857m.  Take half its coefficient (-0.1428571429).
Square it (0.02040816328) and add it to both sides.

Add '0.02040816328' to each side of the equation.
-0.2857142857m + 0.02040816328 + m2 = -0.2857142857 + 0.02040816328

Reorder the terms:
0.02040816328 + -0.2857142857m + m2 = -0.2857142857 + 0.02040816328

Combine like terms: -0.2857142857 + 0.02040816328 = -0.26530612242
0.02040816328 + -0.2857142857m + m2 = -0.26530612242

Factor a perfect square on the left side:
(m + -0.1428571429)(m + -0.1428571429) = -0.26530612242

Can't calculate square root of the right side.
