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

Divide each side by '-4'.
2.25 + -0.75x + x2 = 0

Move the constant term to the right:

Add '-2.25' to each side of the equation.
2.25 + -0.75x + -2.25 + x2 = 0 + -2.25

Reorder the terms:
2.25 + -2.25 + -0.75x + x2 = 0 + -2.25

Combine like terms: 2.25 + -2.25 = 0.00
0.00 + -0.75x + x2 = 0 + -2.25
-0.75x + x2 = 0 + -2.25

Combine like terms: 0 + -2.25 = -2.25
-0.75x + x2 = -2.25

The x term is -0.75x.  Take half its coefficient (-0.375).
