Solving for variable 'x'.

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

Divide each side by '10'.
0.4 + -1.1x + x2 = 0

Move the constant term to the right:

Add '-0.4' to each side of the equation.
0.4 + -1.1x + -0.4 + x2 = 0 + -0.4

Reorder the terms:
0.4 + -0.4 + -1.1x + x2 = 0 + -0.4

Combine like terms: 0.4 + -0.4 = 0.0
0.0 + -1.1x + x2 = 0 + -0.4
-1.1x + x2 = 0 + -0.4

Combine like terms: 0 + -0.4 = -0.4
-1.1x + x2 = -0.4

The x term is -1.1x.  Take half its coefficient (-0.55).
Square it (0.3025) and add it to both sides.

Add '0.3025' to each side of the equation.
-1.1x + 0.3025 + x2 = -0.4 + 0.3025
