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

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

Move the constant term to the right:

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

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

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

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

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 = 1 + 0.09

Reorder the terms:
0.09 + 0.6x + x2 = 1 + 0.09

Combine like terms: 1 + 0.09 = 1.09
0.09 + 0.6x + x2 = 1.09

Factor a perfect square on the left side:
(x + 0.3)(x + 0.3) = 1.09
