Solving for variable 'x'.

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

Divide each side by '3'.
0.01 + -6x + x2 = 0

Move the constant term to the right:

Add '-0.01' to each side of the equation.
0.01 + -6x + -0.01 + x2 = 0 + -0.01

Reorder the terms:
0.01 + -0.01 + -6x + x2 = 0 + -0.01

Combine like terms: 0.01 + -0.01 = 0.00
0.00 + -6x + x2 = 0 + -0.01
-6x + x2 = 0 + -0.01

Combine like terms: 0 + -0.01 = -0.01
-6x + x2 = -0.01

The x term is -6x.  Take half its coefficient (-3).
