Solving for variable 'x'.

Begin completing the square.

Move the constant term to the right:

Add '-0.11' to each side of the equation.
0.11 + 0.66x + -0.11 + x2 = 0 + -0.11

Reorder the terms:
0.11 + -0.11 + 0.66x + x2 = 0 + -0.11

Combine like terms: 0.11 + -0.11 = 0.00
0.00 + 0.66x + x2 = 0 + -0.11
0.66x + x2 = 0 + -0.11

Combine like terms: 0 + -0.11 = -0.11
0.66x + x2 = -0.11

The x term is 0.66x.  Take half its coefficient (0.33).
