Solving for variable 'x'.

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

Divide each side by '-10'.
-0.5 + 0.6x + x2 = 0

Move the constant term to the right:

Add '0.5' to each side of the equation.
-0.5 + 0.6x + 0.5 + x2 = 0 + 0.5

Reorder the terms:
-0.5 + 0.5 + 0.6x + x2 = 0 + 0.5

Combine like terms: -0.5 + 0.5 = 0.0
0.0 + 0.6x + x2 = 0 + 0.5
0.6x + x2 = 0 + 0.5

Combine like terms: 0 + 0.5 = 0.5
0.6x + x2 = 0.5

The x term is 0.6x.  Take half its coefficient (0.3).
Square it (0.09) and add it to both sides.

Add '0.09' to each side of the equation.
0.6x + 0.09 + x2 = 0.5 + 0.09

Reorder the terms:
0.09 + 0.6x + x2 = 0.5 + 0.09

Combine like terms: 0.5 + 0.09 = 0.59
0.09 + 0.6x + x2 = 0.59

Factor a perfect square on the left side:
(x + 0.3)(x + 0.3) = 0.59

Calculate the square root of the right side: 0.768114575
