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

Divide each side by '5'.
-0.6 + -1x + x2 = 0

Move the constant term to the right:

Add '0.6' to each side of the equation.
-0.6 + -1x + 0.6 + x2 = 0 + 0.6

Reorder the terms:
-0.6 + 0.6 + -1x + x2 = 0 + 0.6

Combine like terms: -0.6 + 0.6 = 0.0
0.0 + -1x + x2 = 0 + 0.6
-1x + x2 = 0 + 0.6

Combine like terms: 0 + 0.6 = 0.6
-1x + x2 = 0.6

The x term is -1x.  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.
-1x + 0.25 + x2 = 0.6 + 0.25

Reorder the terms:
0.25 + -1x + x2 = 0.6 + 0.25

Combine like terms: 0.6 + 0.25 = 0.85
0.25 + -1x + x2 = 0.85

Factor a perfect square on the left side:
(x + -0.5)(x + -0.5) = 0.85
