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

Divide each side by '-0.01'.
1700 + -100x + x2 = 0

Move the constant term to the right:

Add '-1700' to each side of the equation.
1700 + -100x + -1700 + x2 = 0 + -1700

Reorder the terms:
1700 + -1700 + -100x + x2 = 0 + -1700

Combine like terms: 1700 + -1700 = 0
0 + -100x + x2 = 0 + -1700
-100x + x2 = 0 + -1700

Combine like terms: 0 + -1700 = -1700
-100x + x2 = -1700

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.
-100x + 0.25 + x2 = -1700 + 0.25

Reorder the terms:
0.25 + -100x + x2 = -1700 + 0.25

Combine like terms: -1700 + 0.25 = -1699.75
0.25 + -100x + x2 = -1699.75

Factor a perfect square on the left side:
(x + 0.5)(x + 0.5) = -1699.75

Can't calculate square root of the right side.

The solution to this equation could not be determined.
