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

Divide each side by '0.01'.
1800 + -106d + d2 = 0

Move the constant term to the right:

Add '-1800' to each side of the equation.
1800 + -106d + -1800 + d2 = 0 + -1800

Reorder the terms:
1800 + -1800 + -106d + d2 = 0 + -1800

Combine like terms: 1800 + -1800 = 0
0 + -106d + d2 = 0 + -1800
-106d + d2 = 0 + -1800

Combine like terms: 0 + -1800 = -1800
-106d + d2 = -1800

The d term is -106d.  Take half its coefficient (-53).
