Solving for variable 'x'.

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

Divide each side by '10'.
0.8 + -0.5x + x2 = 0

Move the constant term to the right:

Add '-0.8' to each side of the equation.
0.8 + -0.5x + -0.8 + x2 = 0 + -0.8

Reorder the terms:
0.8 + -0.8 + -0.5x + x2 = 0 + -0.8

Combine like terms: 0.8 + -0.8 = 0.0
0.0 + -0.5x + x2 = 0 + -0.8
-0.5x + x2 = 0 + -0.8

Combine like terms: 0 + -0.8 = -0.8
-0.5x + x2 = -0.8

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 = -0.8 + 0.0625

Reorder the terms:
0.0625 + -0.5x + x2 = -0.8 + 0.0625

Combine like terms: -0.8 + 0.0625 = -0.7375
0.0625 + -0.5x + x2 = -0.7375

Factor a perfect square on the left side:
(x + -0.25)(x + -0.25) = -0.7375

Can't calculate square root of the right side.
