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

Divide each side by '20'.
0.5 + -0.15x + x2 = 0

Move the constant term to the right:

Add '-0.5' to each side of the equation.
0.5 + -0.15x + -0.5 + x2 = 0 + -0.5

Reorder the terms:
0.5 + -0.5 + -0.15x + x2 = 0 + -0.5

Combine like terms: 0.5 + -0.5 = 0.0
0.0 + -0.15x + x2 = 0 + -0.5
-0.15x + x2 = 0 + -0.5

Combine like terms: 0 + -0.5 = -0.5
-0.15x + x2 = -0.5

The x term is -0.15x.  Take half its coefficient (-0.075).
Square it (0.005625) and add it to both sides.

Add '0.005625' to each side of the equation.
-0.15x + 0.005625 + x2 = -0.5 + 0.005625

Reorder the terms:
0.005625 + -0.15x + x2 = -0.5 + 0.005625

Combine like terms: -0.5 + 0.005625 = -0.494375
0.005625 + -0.15x + x2 = -0.494375

Factor a perfect square on the left side:
(x + -0.075)(x + -0.075) = -0.494375

Can't calculate square root of the right side.

The solution to this equation could not be determined.
