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

Divide each side by '10'.
-0.6 + -0.1x + x2 = 0

Move the constant term to the right:

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

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

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

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

The x term is -0.1x.  Take half its coefficient (-0.05).
Square it (0.0025) and add it to both sides.

Add '0.0025' to each side of the equation.
-0.1x + 0.0025 + x2 = 0.6 + 0.0025

Reorder the terms:
0.0025 + -0.1x + x2 = 0.6 + 0.0025

Combine like terms: 0.6 + 0.0025 = 0.6025
0.0025 + -0.1x + x2 = 0.6025
