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

Divide each side by '5'.
0.8 + -0.6X + X2 = 0

Move the constant term to the right:

Add '-0.8' to each side of the equation.
0.8 + -0.6X + -0.8 + X2 = 0 + -0.8

Reorder the terms:
0.8 + -0.8 + -0.6X + X2 = 0 + -0.8

Combine like terms: 0.8 + -0.8 = 0.0
0.0 + -0.6X + X2 = 0 + -0.8
-0.6X + X2 = 0 + -0.8

Combine like terms: 0 + -0.8 = -0.8
-0.6X + X2 = -0.8

The X term is -0.6X.  Take half its coefficient (-0.3).
Square it (0.09) and add it to both sides.

Add '0.09' to each side of the equation.
-0.6X + 0.09 + X2 = -0.8 + 0.09
