Solving for variable 'x'.

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

Divide each side by '3'.
0.1 + -0.6x + x2 = 0

Move the constant term to the right:

Add '-0.1' to each side of the equation.
0.1 + -0.6x + -0.1 + x2 = 0 + -0.1

Reorder the terms:
0.1 + -0.1 + -0.6x + x2 = 0 + -0.1

Combine like terms: 0.1 + -0.1 = 0.0
0.0 + -0.6x + x2 = 0 + -0.1
-0.6x + x2 = 0 + -0.1

Combine like terms: 0 + -0.1 = -0.1
-0.6x + x2 = -0.1

The x term is -0.6x.  Take half its coefficient (-0.3).
Square it (0.09) and add it to both sides.

Add '0.09' to each side of the equation.
-0.6x + 0.09 + x2 = -0.1 + 0.09
