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

Divide each side by '5'.
0.8 + -0.4x + x2 = 0

Move the constant term to the right:

Add '-0.8' to each side of the equation.
0.8 + -0.4x + -0.8 + x2 = 0 + -0.8

Reorder the terms:
0.8 + -0.8 + -0.4x + x2 = 0 + -0.8

Combine like terms: 0.8 + -0.8 = 0.0
0.0 + -0.4x + x2 = 0 + -0.8
-0.4x + x2 = 0 + -0.8
