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

Divide each side by '10'.
-0.1 + 1.2x + x2 = 0

Move the constant term to the right:

Add '0.1' to each side of the equation.
-0.1 + 1.2x + 0.1 + x2 = 0 + 0.1

Reorder the terms:
-0.1 + 0.1 + 1.2x + x2 = 0 + 0.1

Combine like terms: -0.1 + 0.1 = 0.0
0.0 + 1.2x + x2 = 0 + 0.1
1.2x + x2 = 0 + 0.1

Combine like terms: 0 + 0.1 = 0.1
1.2x + x2 = 0.1

The x term is 1.2x.  Take half its coefficient (0.6).
Square it (0.36) and add it to both sides.

Add '0.36' to each side of the equation.
1.2x + 0.36 + x2 = 0.1 + 0.36
