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 + -1x + x2 = 0

Move the constant term to the right:

Add '2.25' to each side of the equation.
-2.25 + -1x + 2.25 + x2 = 0 + 2.25

Reorder the terms:
-2.25 + 2.25 + -1x + x2 = 0 + 2.25

Combine like terms: -2.25 + 2.25 = 0.00
0.00 + -1x + x2 = 0 + 2.25
-1x + x2 = 0 + 2.25

Combine like terms: 0 + 2.25 = 2.25
-1x + x2 = 2.25

The x term is -1x.  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.
-1x + 0.25 + x2 = 2.25 + 0.25

Reorder the terms:
0.25 + -1x + x2 = 2.25 + 0.25

Combine like terms: 2.25 + 0.25 = 2.5
0.25 + -1x + x2 = 2.5
