Solving for variable 'x'.

Begin completing the square.  Divide all terms by
-1 the coefficient of the squared term: 

Divide each side by '-1'.
-9 + x + x2 = 0

Move the constant term to the right:

Add '9' to each side of the equation.
-9 + x + 9 + x2 = 0 + 9

Reorder the terms:
-9 + 9 + x + x2 = 0 + 9

Combine like terms: -9 + 9 = 0
0 + x + x2 = 0 + 9
x + x2 = 0 + 9

Combine like terms: 0 + 9 = 9
x + x2 = 9

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 = 9 + 0.25

Combine like terms:  + 0.25 = 1.25
1.25 + x2 = 9 + 0.25

Combine like terms: 9 + 0.25 = 9.25
1.25 + x2 = 9.25

Factor a perfect square on the left side:
(x + 0.5)(x + 0.5) = 9.25
