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

Divide each side by '10'.
0.5 + -1.6x + x2 = 0.0

Move the constant term to the right:

Add '-0.5' to each side of the equation.
0.5 + -1.6x + -0.5 + x2 = 0.0 + -0.5

Reorder the terms:
0.5 + -0.5 + -1.6x + x2 = 0.0 + -0.5

Combine like terms: 0.5 + -0.5 = 0.0
0.0 + -1.6x + x2 = 0.0 + -0.5
-1.6x + x2 = 0.0 + -0.5

Combine like terms: 0.0 + -0.5 = -0.5
-1.6x + x2 = -0.5

The x term is -1.6x.  Take half its coefficient (-0.8).
Square it (0.64) and add it to both sides.

Add '0.64' to each side of the equation.
-1.6x + 0.64 + x2 = -0.5 + 0.64

Reorder the terms:
0.64 + -1.6x + x2 = -0.5 + 0.64

Combine like terms: -0.5 + 0.64 = 0.14
0.64 + -1.6x + x2 = 0.14
