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

Divide each side by '4'.
3.25 + -4.5x + x2 = 0

Move the constant term to the right:

Add '-3.25' to each side of the equation.
3.25 + -4.5x + -3.25 + x2 = 0 + -3.25

Reorder the terms:
3.25 + -3.25 + -4.5x + x2 = 0 + -3.25

Combine like terms: 3.25 + -3.25 = 0.00
0.00 + -4.5x + x2 = 0 + -3.25
-4.5x + x2 = 0 + -3.25

Combine like terms: 0 + -3.25 = -3.25
-4.5x + x2 = -3.25

The x term is -4.5x.  Take half its coefficient (-2.25).
