Solving for variable 'x'.

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

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

Move the constant term to the right:

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

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

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

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

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 = -0.3 + 0.36

Reorder the terms:
0.36 + -1.2x + x2 = -0.3 + 0.36

Combine like terms: -0.3 + 0.36 = 0.06
0.36 + -1.2x + x2 = 0.06
