Solving for variable 'x'.

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

Divide each side by '2'.
-0.5 + -5x + x2 = 0

Move the constant term to the right:

Add '0.5' to each side of the equation.
-0.5 + -5x + 0.5 + x2 = 0 + 0.5

Reorder the terms:
-0.5 + 0.5 + -5x + x2 = 0 + 0.5

Combine like terms: -0.5 + 0.5 = 0.0
0.0 + -5x + x2 = 0 + 0.5
-5x + x2 = 0 + 0.5

Combine like terms: 0 + 0.5 = 0.5
-5x + x2 = 0.5

The x term is -5x.  Take half its coefficient (-2.5).
Square it (6.25) and add it to both sides.

Add '6.25' to each side of the equation.
-5x + 6.25 + x2 = 0.5 + 6.25

Reorder the terms:
6.25 + -5x + x2 = 0.5 + 6.25

Combine like terms: 0.5 + 6.25 = 6.75
6.25 + -5x + x2 = 6.75

Factor a perfect square on the left side:
(x + -2.5)(x + -2.5) = 6.75
