Solving for variable 'x'.

Begin completing the square.  Divide all terms by
-2 the coefficient of the squared term: 

Divide each side by '-2'.
-8.5 + 4x + x2 = 0

Move the constant term to the right:

Add '8.5' to each side of the equation.
-8.5 + 4x + 8.5 + x2 = 0 + 8.5

Reorder the terms:
-8.5 + 8.5 + 4x + x2 = 0 + 8.5

Combine like terms: -8.5 + 8.5 = 0.0
0.0 + 4x + x2 = 0 + 8.5
4x + x2 = 0 + 8.5

Combine like terms: 0 + 8.5 = 8.5
4x + x2 = 8.5

The x term is 4x.  Take half its coefficient (2).
Square it (4) and add it to both sides.

Add '4' to each side of the equation.
4x + 4 + x2 = 8.5 + 4

Reorder the terms:
4 + 4x + x2 = 8.5 + 4

Combine like terms: 8.5 + 4 = 12.5
4 + 4x + x2 = 12.5

Factor a perfect square on the left side:
(x + 2)(x + 2) = 12.5

Calculate the square root of the right side: 3.535533906
