4 the coefficient of the squared term: 

Divide each side by '4'.
-2.25 + 0.5x + x2 = 0

Move the constant term to the right:

Add '2.25' to each side of the equation.
-2.25 + 0.5x + 2.25 + x2 = 0 + 2.25

Reorder the terms:
-2.25 + 2.25 + 0.5x + x2 = 0 + 2.25

Combine like terms: -2.25 + 2.25 = 0.00
0.00 + 0.5x + x2 = 0 + 2.25
0.5x + x2 = 0 + 2.25

Combine like terms: 0 + 2.25 = 2.25
0.5x + x2 = 2.25

The x term is 0.5x.  Take half its coefficient (0.25).
