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).
