Solving for variable 'x'.

Begin completing the square.

Move the constant term to the right:

Add '-33' to each side of the equation.
33 + 9x + -33 + x2 = 0 + -33

Reorder the terms:
33 + -33 + 9x + x2 = 0 + -33

Combine like terms: 33 + -33 = 0
0 + 9x + x2 = 0 + -33
9x + x2 = 0 + -33

Combine like terms: 0 + -33 = -33
9x + x2 = -33

The x term is 9x.  Take half its coefficient (4.5).
Square it (20.25) and add it to both sides.

Add '20.25' to each side of the equation.
9x + 20.25 + x2 = -33 + 20.25

Reorder the terms:
20.25 + 9x + x2 = -33 + 20.25

Combine like terms: -33 + 20.25 = -12.75
20.25 + 9x + x2 = -12.75

Factor a perfect square on the left side:
(x + 4.5)(x + 4.5) = -12.75

Can't calculate square root of the right side.

The solution to this equation could not be determined.
