-27 + x + -0.01x2 = 0 + -1x + x + 0.01x2 + -0.01x2
-27 + x + -0.01x2 = -1x + x + 0.01x2 + -0.01x2

Combine like terms: -1x + x = 0
-27 + x + -0.01x2 = 0 + 0.01x2 + -0.01x2
-27 + x + -0.01x2 = 0.01x2 + -0.01x2

Combine like terms: 0.01x2 + -0.01x2 = 0.00
-27 + 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'.
2700 + -100x + x2 = 0

Move the constant term to the right:

Add '-2700' to each side of the equation.
2700 + -100x + -2700 + x2 = 0 + -2700

Reorder the terms:
2700 + -2700 + -100x + x2 = 0 + -2700

Combine like terms: 2700 + -2700 = 0
0 + -100x + x2 = 0 + -2700
-100x + x2 = 0 + -2700

Combine like terms: 0 + -2700 = -2700
-100x + x2 = -2700

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 = -2700 + 0.25

Reorder the terms:
0.25 + -100x + x2 = -2700 + 0.25

Combine like terms: -2700 + 0.25 = -2699.75
0.25 + -100x + x2 = -2699.75

Factor a perfect square on the left side:
(x + 0.5)(x + 0.5) = -2699.75

Can't calculate square root of the right side.

The solution to this equation could not be determined.
