Solving for variable 'x'.

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

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

Move the constant term to the right:

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

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

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

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

The x term is x.  Take half its coefficient (0.5).
Square it (0.25) and add it to both sides.

Add '0.25' to each side of the equation.
 + 0.25 + x2 = -2.25 + 0.25
