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

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

Move the constant term to the right:

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

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

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

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

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