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

Divide each side by '20'.
-6.65 + -3.4x + x2 = 0.0

Move the constant term to the right:

Add '6.65' to each side of the equation.
-6.65 + -3.4x + 6.65 + x2 = 0.0 + 6.65

Reorder the terms:
-6.65 + 6.65 + -3.4x + x2 = 0.0 + 6.65

Combine like terms: -6.65 + 6.65 = 0.00
0.00 + -3.4x + x2 = 0.0 + 6.65
-3.4x + x2 = 0.0 + 6.65

Combine like terms: 0.0 + 6.65 = 6.65
-3.4x + x2 = 6.65

The x term is -3.4x.  Take half its coefficient (-1.7).
Square it (2.89) and add it to both sides.

Add '2.89' to each side of the equation.
-3.4x + 2.89 + x2 = 6.65 + 2.89
