Divide each side by '20'.
1.65 + -0.45x + x2 = 0

Move the constant term to the right:

Add '-1.65' to each side of the equation.
1.65 + -0.45x + -1.65 + x2 = 0 + -1.65

Reorder the terms:
1.65 + -1.65 + -0.45x + x2 = 0 + -1.65

Combine like terms: 1.65 + -1.65 = 0.00
0.00 + -0.45x + x2 = 0 + -1.65
-0.45x + x2 = 0 + -1.65

Combine like terms: 0 + -1.65 = -1.65
-0.45x + x2 = -1.65

The x term is -0.45x.  Take half its coefficient (-0.225).
