Solving for variable 'x'.

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

Divide each side by '5'.
0.01 + -0.4x + x2 = 0

Move the constant term to the right:

Add '-0.01' to each side of the equation.
0.01 + -0.4x + -0.01 + x2 = 0 + -0.01

Reorder the terms:
0.01 + -0.01 + -0.4x + x2 = 0 + -0.01

Combine like terms: 0.01 + -0.01 = 0.00
0.00 + -0.4x + x2 = 0 + -0.01
-0.4x + x2 = 0 + -0.01

Combine like terms: 0 + -0.01 = -0.01
-0.4x + x2 = -0.01

The x term is -0.4x.  Take half its coefficient (-0.2).
Square it (0.04) and add it to both sides.

Add '0.04' to each side of the equation.
-0.4x + 0.04 + x2 = -0.01 + 0.04

Reorder the terms:
0.04 + -0.4x + x2 = -0.01 + 0.04

Combine like terms: -0.01 + 0.04 = 0.03
0.04 + -0.4x + x2 = 0.03
