Solving for variable 'm'.

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

Divide each side by '2'.
-2 + 13.5m + m2 = 0

Move the constant term to the right:

Add '2' to each side of the equation.
-2 + 13.5m + 2 + m2 = 0 + 2

Reorder the terms:
-2 + 2 + 13.5m + m2 = 0 + 2

Combine like terms: -2 + 2 = 0
0 + 13.5m + m2 = 0 + 2
13.5m + m2 = 0 + 2

Combine like terms: 0 + 2 = 2
13.5m + m2 = 2

The m term is 13.5m.  Take half its coefficient (6.75).
Square it (45.5625) and add it to both sides.

Add '45.5625' to each side of the equation.
13.5m + 45.5625 + m2 = 2 + 45.5625

Reorder the terms:
45.5625 + 13.5m + m2 = 2 + 45.5625

Combine like terms: 2 + 45.5625 = 47.5625
45.5625 + 13.5m + m2 = 47.5625
