Solving for variable 'x'.

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

Divide each side by '20'.
-0.25 + 0.15x + x2 = 0.0

Move the constant term to the right:

Add '0.25' to each side of the equation.
-0.25 + 0.15x + 0.25 + x2 = 0.0 + 0.25

Reorder the terms:
-0.25 + 0.25 + 0.15x + x2 = 0.0 + 0.25

Combine like terms: -0.25 + 0.25 = 0.00
0.00 + 0.15x + x2 = 0.0 + 0.25
0.15x + x2 = 0.0 + 0.25

Combine like terms: 0.0 + 0.25 = 0.25
0.15x + x2 = 0.25

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 = 0.25 + 0.005625

Reorder the terms:
0.005625 + 0.15x + x2 = 0.25 + 0.005625

Combine like terms: 0.25 + 0.005625 = 0.255625
0.005625 + 0.15x + x2 = 0.255625
