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

Divide each side by '5'.
-0.2 + x + x2 = 0

Move the constant term to the right:

Add '0.2' to each side of the equation.
-0.2 + x + 0.2 + x2 = 0 + 0.2

Reorder the terms:
-0.2 + 0.2 + x + x2 = 0 + 0.2

Combine like terms: -0.2 + 0.2 = 0.0
0.0 + x + x2 = 0 + 0.2
x + x2 = 0 + 0.2

Combine like terms: 0 + 0.2 = 0.2
x + x2 = 0.2

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

Add '0.25' to each side of the equation.
 + 0.25 + x2 = 0.2 + 0.25

Combine like terms:  + 0.25 = 1.25
1.25 + x2 = 0.2 + 0.25

Combine like terms: 0.2 + 0.25 = 0.45
1.25 + x2 = 0.45

Factor a perfect square on the left side:
(x + 0.5)(x + 0.5) = 0.45

Calculate the square root of the right side: 0.670820393

Break this problem into two subproblems by setting 
(x + 0.5) equal to 0.670820393 and -0.670820393.
