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

Divide each side by '10'.
0.2 + -1.7x + x2 = 0

Move the constant term to the right:

Add '-0.2' to each side of the equation.
0.2 + -1.7x + -0.2 + x2 = 0 + -0.2

Reorder the terms:
0.2 + -0.2 + -1.7x + x2 = 0 + -0.2

Combine like terms: 0.2 + -0.2 = 0.0
0.0 + -1.7x + x2 = 0 + -0.2
-1.7x + x2 = 0 + -0.2

Combine like terms: 0 + -0.2 = -0.2
-1.7x + x2 = -0.2

The x term is -1.7x.  Take half its coefficient (-0.85).
Square it (0.7225) and add it to both sides.

Add '0.7225' to each side of the equation.
-1.7x + 0.7225 + x2 = -0.2 + 0.7225

Reorder the terms:
0.7225 + -1.7x + x2 = -0.2 + 0.7225

Combine like terms: -0.2 + 0.7225 = 0.5225
0.7225 + -1.7x + x2 = 0.5225
