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 = 0.3225
0.0225 + 0.3x + x2 = 0.3225

Factor a perfect square on the left side:
(x + 0.15)(x + 0.15) = 0.3225

Calculate the square root of the right side: 0.567890835
