Solving for variable 'x'.

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

Divide each side by '10'.
-0.3 + -0.6x + x2 = 0

Move the constant term to the right:

Add '0.3' to each side of the equation.
-0.3 + -0.6x + 0.3 + x2 = 0 + 0.3

Reorder the terms:
-0.3 + 0.3 + -0.6x + x2 = 0 + 0.3

Combine like terms: -0.3 + 0.3 = 0.0
0.0 + -0.6x + x2 = 0 + 0.3
-0.6x + x2 = 0 + 0.3

Combine like terms: 0 + 0.3 = 0.3
-0.6x + x2 = 0.3

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 = 0.3 + 0.09

Reorder the terms:
0.09 + -0.6x + x2 = 0.3 + 0.09

Combine like terms: 0.3 + 0.09 = 0.39
0.09 + -0.6x + x2 = 0.39

Factor a perfect square on the left side:
((x) + -0.3)((x) + -0.3) = 0.39
