Solving for variable 'm'.

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

Divide each side by '4'.
-6.25 + m + m2 = 0

Move the constant term to the right:

Add '6.25' to each side of the equation.
-6.25 + m + 6.25 + m2 = 0 + 6.25

Reorder the terms:
-6.25 + 6.25 + m + m2 = 0 + 6.25

Combine like terms: -6.25 + 6.25 = 0.00
0.00 + m + m2 = 0 + 6.25
m + m2 = 0 + 6.25

Combine like terms: 0 + 6.25 = 6.25
m + m2 = 6.25

The m term is m.  Take half its coefficient (0.5).
Square it (0.25) and add it to both sides.

Add '0.25' to each side of the equation.
 + 0.25 + m2 = 6.25 + 0.25

Combine like terms:  + 0.25 = 1.25
1.25 + m2 = 6.25 + 0.25

Combine like terms: 6.25 + 0.25 = 6.5
1.25 + m2 = 6.5

Factor a perfect square on the left side:
(m + 0.5)(m + 0.5) = 6.5
