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

Divide each side by '100'.
-0.02 + 0.01x + x2 = 0.00

Move the constant term to the right:

Add '0.02' to each side of the equation.
-0.02 + 0.01x + 0.02 + x2 = 0.00 + 0.02

Reorder the terms:
-0.02 + 0.02 + 0.01x + x2 = 0.00 + 0.02

Combine like terms: -0.02 + 0.02 = 0.00
0.00 + 0.01x + x2 = 0.00 + 0.02
0.01x + x2 = 0.00 + 0.02

Combine like terms: 0.00 + 0.02 = 0.02
0.01x + x2 = 0.02

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.
0.01x + 0.25 + x2 = 0.02 + 0.25

Reorder the terms:
0.25 + 0.01x + x2 = 0.02 + 0.25

Combine like terms: 0.02 + 0.25 = 0.27
0.25 + 0.01x + x2 = 0.27
