Solving for variable 'm'.

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

Divide each side by '-2'.
0.5 + -4.5m + m2 = 0

Move the constant term to the right:

Add '-0.5' to each side of the equation.
0.5 + -4.5m + -0.5 + m2 = 0 + -0.5

Reorder the terms:
0.5 + -0.5 + -4.5m + m2 = 0 + -0.5

Combine like terms: 0.5 + -0.5 = 0.0
0.0 + -4.5m + m2 = 0 + -0.5
-4.5m + m2 = 0 + -0.5

Combine like terms: 0 + -0.5 = -0.5
-4.5m + m2 = -0.5

The m term is -4.5m.  Take half its coefficient (-2.25).
Square it (5.0625) and add it to both sides.

Add '5.0625' to each side of the equation.
-4.5m + 5.0625 + m2 = -0.5 + 5.0625

Reorder the terms:
5.0625 + -4.5m + m2 = -0.5 + 5.0625

Combine like terms: -0.5 + 5.0625 = 4.5625
5.0625 + -4.5m + m2 = 4.5625

Factor a perfect square on the left side:
(m + -2.25)(m + -2.25) = 4.5625

Calculate the square root of the right side: 2.136000936
