Solving for variable 'm'.

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

Divide each side by '4'.
-10.75 + -1m + m2 = 0

Move the constant term to the right:

Add '10.75' to each side of the equation.
-10.75 + -1m + 10.75 + m2 = 0 + 10.75

Reorder the terms:
-10.75 + 10.75 + -1m + m2 = 0 + 10.75

Combine like terms: -10.75 + 10.75 = 0.00
0.00 + -1m + m2 = 0 + 10.75
-1m + m2 = 0 + 10.75

Combine like terms: 0 + 10.75 = 10.75
-1m + m2 = 10.75

The m term is -1m.  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.
-1m + 0.25 + m2 = 10.75 + 0.25

Reorder the terms:
0.25 + -1m + m2 = 10.75 + 0.25

Combine like terms: 10.75 + 0.25 = 11
0.25 + -1m + m2 = 11

Factor a perfect square on the left side:
(m + -0.5)(m + -0.5) = 11

Calculate the square root of the right side: 3.31662479
