Solving for variable 'x'.

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

Divide each side by '-10'.
0.9 + -1.2x + x2 = 0

Move the constant term to the right:

Add '-0.9' to each side of the equation.
0.9 + -1.2x + -0.9 + x2 = 0 + -0.9

Reorder the terms:
0.9 + -0.9 + -1.2x + x2 = 0 + -0.9

Combine like terms: 0.9 + -0.9 = 0.0
0.0 + -1.2x + x2 = 0 + -0.9
-1.2x + x2 = 0 + -0.9

0.36 + -1.2x + x2 = -0.9 + 0.36

Combine like terms: -0.9 + 0.36 = -0.54
0.36 + -1.2x + x2 = -0.54

Factor a perfect square on the left side:
(x + -0.6)(x + -0.6) = -0.54

Can't calculate square root of the right side.
