Solving for variable 'x'.

Reorder the terms:
-237 + x + -1x2 = 237 + -237

Combine like terms: 237 + -237 = 0
-237 + x + -1x2 = 0

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

Divide each side by '-1'.
237 + -1x + x2 = 0

Move the constant term to the right:

Add '-237' to each side of the equation.
237 + -1x + -237 + x2 = 0 + -237

Reorder the terms:
237 + -237 + -1x + x2 = 0 + -237

Combine like terms: 237 + -237 = 0
0 + -1x + x2 = 0 + -237
-1x + x2 = 0 + -237

-1x + x2 = -237

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.
-1x + 0.25 + x2 = -237 + 0.25

Reorder the terms:
0.25 + -1x + x2 = -237 + 0.25

Combine like terms: -237 + 0.25 = -236.75
0.25 + -1x + x2 = -236.75

Factor a perfect square on the left side:
(x + 0.5)(x + 0.5) = -236.75

Can't calculate square root of the right side.
