Solving for variable 'm'.

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

Divide each side by '2'.
13 + 7.5m + m2 = 0

Move the constant term to the right:

Add '-13' to each side of the equation.
13 + 7.5m + -13 + m2 = 0 + -13

Reorder the terms:
13 + -13 + 7.5m + m2 = 0 + -13

Combine like terms: 13 + -13 = 0
0 + 7.5m + m2 = 0 + -13
7.5m + m2 = 0 + -13

Combine like terms: 0 + -13 = -13
7.5m + m2 = -13

The m term is 7.5m.  Take half its coefficient (3.75).
Square it (14.0625) and add it to both sides.

Add '14.0625' to each side of the equation.
7.5m + 14.0625 + m2 = -13 + 14.0625

Reorder the terms:
14.0625 + 7.5m + m2 = -13 + 14.0625

Combine like terms: -13 + 14.0625 = 1.0625
14.0625 + 7.5m + m2 = 1.0625

Factor a perfect square on the left side:
(m + 3.75)(m + 3.75) = 1.0625

Calculate the square root of the right side: 1.030776406
