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

Divide each side by '-10'.
-0.3 + -2.3x + x2 = 0.0

Move the constant term to the right:

Add '0.3' to each side of the equation.
-0.3 + -2.3x + 0.3 + x2 = 0.0 + 0.3

Reorder the terms:
-0.3 + 0.3 + -2.3x + x2 = 0.0 + 0.3

Combine like terms: -0.3 + 0.3 = 0.0
0.0 + -2.3x + x2 = 0.0 + 0.3
-2.3x + x2 = 0.0 + 0.3

Combine like terms: 0.0 + 0.3 = 0.3
-2.3x + x2 = 0.3

The x term is -2.3x.  Take half its coefficient (-1.15).
Square it (1.3225) and add it to both sides.

Add '1.3225' to each side of the equation.
-2.3x + 1.3225 + x2 = 0.3 + 1.3225
