Solving for variable 'x'.

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

Divide each side by '2'.
-26 + -0.5x + x2 = 0

Move the constant term to the right:

Add '26' to each side of the equation.
-26 + -0.5x + 26 + x2 = 0 + 26

Reorder the terms:
-26 + 26 + -0.5x + x2 = 0 + 26

Combine like terms: -26 + 26 = 0
0 + -0.5x + x2 = 0 + 26
-0.5x + x2 = 0 + 26

Combine like terms: 0 + 26 = 26
-0.5x + x2 = 26

The x term is -0.5x.  Take half its coefficient (-0.25).
Square it (0.0625) and add it to both sides.

Add '0.0625' to each side of the equation.
-0.5x + 0.0625 + x2 = 26 + 0.0625

Reorder the terms:
0.0625 + -0.5x + x2 = 26 + 0.0625

Combine like terms: 26 + 0.0625 = 26.0625
0.0625 + -0.5x + x2 = 26.0625
