Solving for variable 'x'.

Begin completing the square.

Move the constant term to the right:

Add '-0.5' to each side of the equation.
0.5 + 1.2x + -0.5 + x2 = 0 + -0.5

Reorder the terms:
0.5 + -0.5 + 1.2x + x2 = 0 + -0.5

Combine like terms: 0.5 + -0.5 = 0.0
0.0 + 1.2x + x2 = 0 + -0.5
1.2x + x2 = 0 + -0.5

Combine like terms: 0 + -0.5 = -0.5
1.2x + x2 = -0.5

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 = -0.5 + 0.36
