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

Divide each side by '-10'.
1.2 + -0.3x + x2 = 0

Move the constant term to the right:

Add '-1.2' to each side of the equation.
1.2 + -0.3x + -1.2 + x2 = 0 + -1.2

Reorder the terms:
1.2 + -1.2 + -0.3x + x2 = 0 + -1.2

Combine like terms: 1.2 + -1.2 = 0.0
0.0 + -0.3x + x2 = 0 + -1.2
-0.3x + x2 = 0 + -1.2

Combine like terms: 0 + -1.2 = -1.2
-0.3x + x2 = -1.2

The x term is -0.3x.  Take half its coefficient (-0.15).
Square it (0.0225) and add it to both sides.

Add '0.0225' to each side of the equation.
-0.3x + 0.0225 + x2 = -1.2 + 0.0225

Reorder the terms:
0.0225 + -0.3x + x2 = -1.2 + 0.0225

Combine like terms: -1.2 + 0.0225 = -1.1775
0.0225 + -0.3x + x2 = -1.1775

Factor a perfect square on the left side:
(x + -0.15)(x + -0.15) = -1.1775

Can't calculate square root of the right side.
