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

Divide each side by '10'.
0.9 + -0.2x + x2 = 0

Move the constant term to the right:

Add '-0.9' to each side of the equation.
0.9 + -0.2x + -0.9 + x2 = 0 + -0.9

Reorder the terms:
0.9 + -0.9 + -0.2x + x2 = 0 + -0.9

Combine like terms: 0.9 + -0.9 = 0.0
0.0 + -0.2x + x2 = 0 + -0.9
-0.2x + x2 = 0 + -0.9

Combine like terms: 0 + -0.9 = -0.9
-0.2x + x2 = -0.9

The x term is -0.2x.  Take half its coefficient (-0.1).
Square it (0.01) and add it to both sides.

Add '0.01' to each side of the equation.
-0.2x + 0.01 + x2 = -0.9 + 0.01
