Simplifying
0 = 0.01x2 + -1x + 2

Reorder the terms:
0 = 2 + -1x + 0.01x2

Solving
0 = 2 + -1x + 0.01x2

Solving for variable 'x'.

Combine like terms: 0 + -2 = -2
-2 + x + -0.01x2 = 2 + -1x + 0.01x2 + -2 + x + -0.01x2

Reorder the terms:
-2 + x + -0.01x2 = 2 + -2 + -1x + x + 0.01x2 + -0.01x2

Combine like terms: 2 + -2 = 0
-2 + x + -0.01x2 = 0 + -1x + x + 0.01x2 + -0.01x2
-2 + x + -0.01x2 = -1x + x + 0.01x2 + -0.01x2

Combine like terms: -1x + x = 0
-2 + x + -0.01x2 = 0 + 0.01x2 + -0.01x2
-2 + x + -0.01x2 = 0.01x2 + -0.01x2

Combine like terms: 0.01x2 + -0.01x2 = 0.00
-2 + x + -0.01x2 = 0.00

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

Divide each side by '-0.01'.
200 + -100x + x2 = 0

Move the constant term to the right:

Add '-200' to each side of the equation.
200 + -100x + -200 + x2 = 0 + -200

Reorder the terms:
200 + -200 + -100x + x2 = 0 + -200

Combine like terms: 200 + -200 = 0
0 + -100x + x2 = 0 + -200
-100x + x2 = 0 + -200

Combine like terms: 0 + -200 = -200
-100x + x2 = -200

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 = -200 + 0.25

Reorder the terms:
0.25 + -100x + x2 = -200 + 0.25

Combine like terms: -200 + 0.25 = -199.75
0.25 + -100x + x2 = -199.75

Factor a perfect square on the left side:
(x + 0.5)(x + 0.5) = -199.75

Can't calculate square root of the right side.

The solution to this equation could not be determined.
