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

Divide each side by '25'.
-0.08 + -0.04x + x2 = 0

Move the constant term to the right:

Add '0.08' to each side of the equation.
-0.08 + -0.04x + 0.08 + x2 = 0 + 0.08

Reorder the terms:
-0.08 + 0.08 + -0.04x + x2 = 0 + 0.08

Combine like terms: -0.08 + 0.08 = 0.00
0.00 + -0.04x + x2 = 0 + 0.08
-0.04x + x2 = 0 + 0.08

Combine like terms: 0 + 0.08 = 0.08
-0.04x + x2 = 0.08

The x term is -0.04x.  Take half its coefficient (-0.02).
Square it (0.0004) and add it to both sides.

Add '0.0004' to each side of the equation.
-0.04x + 0.0004 + x2 = 0.08 + 0.0004

Reorder the terms:
0.0004 + -0.04x + x2 = 0.08 + 0.0004

Combine like terms: 0.08 + 0.0004 = 0.0804
0.0004 + -0.04x + x2 = 0.0804
