Solving for variable 'x'.

Begin completing the square.  Divide all terms by
-10 the coefficient of the squared term: 

Divide each side by '-10'.
-0.1 + -0.1x + x2 = 0

Move the constant term to the right:

Add '0.1' to each side of the equation.
-0.1 + -0.1x + 0.1 + x2 = 0 + 0.1

Reorder the terms:
-0.1 + 0.1 + -0.1x + x2 = 0 + 0.1

Combine like terms: -0.1 + 0.1 = 0.0
0.0 + -0.1x + x2 = 0 + 0.1
-0.1x + x2 = 0 + 0.1

Combine like terms: 0 + 0.1 = 0.1
-0.1x + x2 = 0.1

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.
-0.1x + 0.25 + x2 = 0.1 + 0.25

Reorder the terms:
0.25 + -0.1x + x2 = 0.1 + 0.25

Combine like terms: 0.1 + 0.25 = 0.35
0.25 + -0.1x + x2 = 0.35

Factor a perfect square on the left side:
(x + 0.5)(x + 0.5) = 0.35

Calculate the square root of the right side: 0.591607978
