Solving for variable 'm'.

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

Divide each side by '5'.
2.6 + -6.6m + m2 = 0

Move the constant term to the right:

Add '-2.6' to each side of the equation.
2.6 + -6.6m + -2.6 + m2 = 0 + -2.6

Reorder the terms:
2.6 + -2.6 + -6.6m + m2 = 0 + -2.6

Combine like terms: 2.6 + -2.6 = 0.0
0.0 + -6.6m + m2 = 0 + -2.6
-6.6m + m2 = 0 + -2.6

Combine like terms: 0 + -2.6 = -2.6
-6.6m + m2 = -2.6

The m term is -6.6m.  Take half its coefficient (-3.3).
Square it (10.89) and add it to both sides.

Add '10.89' to each side of the equation.
-6.6m + 10.89 + m2 = -2.6 + 10.89

Reorder the terms:
10.89 + -6.6m + m2 = -2.6 + 10.89

Combine like terms: -2.6 + 10.89 = 8.29
10.89 + -6.6m + m2 = 8.29

Factor a perfect square on the left side:
(m + -3.3)(m + -3.3) = 8.29

Calculate the square root of the right side: 2.87923601
