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

Divide each side by '20'.
1.15 + -2.2x + x2 = 0

Move the constant term to the right:

Add '-1.15' to each side of the equation.
1.15 + -2.2x + -1.15 + x2 = 0 + -1.15

Reorder the terms:
1.15 + -1.15 + -2.2x + x2 = 0 + -1.15

Combine like terms: 1.15 + -1.15 = 0.00
0.00 + -2.2x + x2 = 0 + -1.15
-2.2x + x2 = 0 + -1.15

Combine like terms: 0 + -1.15 = -1.15
-2.2x + x2 = -1.15

The x term is -2.2x.  Take half its coefficient (-1.1).
Square it (1.21) and add it to both sides.

Add '1.21' to each side of the equation.
-2.2x + 1.21 + x2 = -1.15 + 1.21
