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

Divide each side by '-5'.
-0.6 + -2x + x2 = 0

Move the constant term to the right:

Add '0.6' to each side of the equation.
-0.6 + -2x + 0.6 + x2 = 0 + 0.6

Reorder the terms:
-0.6 + 0.6 + -2x + x2 = 0 + 0.6

Combine like terms: -0.6 + 0.6 = 0.0
0.0 + -2x + x2 = 0 + 0.6
-2x + x2 = 0 + 0.6

Combine like terms: 0 + 0.6 = 0.6
-2x + x2 = 0.6

The x term is -2x.  Take half its coefficient (-1).
Square it (1) and add it to both sides.

Add '1' to each side of the equation.
-2x + 1 + x2 = 0.6 + 1

Reorder the terms:
1 + -2x + x2 = 0.6 + 1

Combine like terms: 0.6 + 1 = 1.6
1 + -2x + x2 = 1.6

Factor a perfect square on the left side:
(x + -1)(x + -1) = 1.6

Calculate the square root of the right side: 1.264911064

Break this problem into two subproblems by setting 
(x + -1) equal to 1.264911064 and -1.264911064.
