Solving for variable 'x'.

Begin completing the square.

Move the constant term to the right:

Add '-111' to each side of the equation.
111 + -18x + -111 + x2 = 0 + -111

Reorder the terms:
111 + -111 + -18x + x2 = 0 + -111

Combine like terms: 111 + -111 = 0
0 + -18x + x2 = 0 + -111
-18x + x2 = 0 + -111

Combine like terms: 0 + -111 = -111
-18x + x2 = -111

The x term is -18x.  Take half its coefficient (-9).
Square it (81) and add it to both sides.

Add '81' to each side of the equation.
-18x + 81 + x2 = -111 + 81

Reorder the terms:
81 + -18x + x2 = -111 + 81

Combine like terms: -111 + 81 = -30
81 + -18x + x2 = -30

Factor a perfect square on the left side:
(x + -9)(x + -9) = -30

Can't calculate square root of the right side.
