Solving for variable 'x'.

Begin completing the square.  Divide all terms by
-5 the coefficient of the squared term: 

Divide each side by '-5'.
-0.6 + -0.6x + x2 = 0

Move the constant term to the right:

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

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

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

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

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 = 0.6 + 0.09

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

Combine like terms: 0.6 + 0.09 = 0.69
0.09 + -0.6x + x2 = 0.69

Factor a perfect square on the left side:
(x + -0.3)(x + -0.3) = 0.69

Calculate the square root of the right side: 0.830662386
