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

Divide each side by '-2'.
5.5 + -4x + x2 = 0

Move the constant term to the right:

Add '-5.5' to each side of the equation.
5.5 + -4x + -5.5 + x2 = 0 + -5.5

Reorder the terms:
5.5 + -5.5 + -4x + x2 = 0 + -5.5

Combine like terms: 5.5 + -5.5 = 0.0
0.0 + -4x + x2 = 0 + -5.5
-4x + x2 = 0 + -5.5

Combine like terms: 0 + -5.5 = -5.5
-4x + x2 = -5.5

The x term is -4x.  Take half its coefficient (-2).
Square it (4) and add it to both sides.
