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 + -0.3x + x2 = 0.0

Move the constant term to the right:

Add '-0.3' to each side of the equation.
0.3 + -0.3x + -0.3 + x2 = 0.0 + -0.3

Reorder the terms:
0.3 + -0.3 + -0.3x + x2 = 0.0 + -0.3

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

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

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 = -0.3 + 0.0225

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

Combine like terms: -0.3 + 0.0225 = -0.2775
0.0225 + -0.3x + x2 = -0.2775

Factor a perfect square on the left side:
(x + -0.15)(x + -0.15) = -0.2775

Can't calculate square root of the right side.
