Solving
0.2 + 0.3x + x2 = 0

Solving for variable 'x'.

Begin completing the square.

Move the constant term to the right:

Add '-0.2' to each side of the equation.
0.2 + 0.3x + -0.2 + x2 = 0 + -0.2

Reorder the terms:
0.2 + -0.2 + 0.3x + x2 = 0 + -0.2

Combine like terms: 0.2 + -0.2 = 0.0
0.0 + 0.3x + x2 = 0 + -0.2
0.3x + x2 = 0 + -0.2

Combine like terms: 0 + -0.2 = -0.2
0.3x + x2 = -0.2

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 = -0.2 + 0.0225

Reorder the terms:
0.0225 + 0.3x + x2 = -0.2 + 0.0225

Combine like terms: -0.2 + 0.0225 = -0.1775
0.0225 + 0.3x + x2 = -0.1775

Factor a perfect square on the left side:
(x + 0.15)(x + 0.15) = -0.1775

Can't calculate square root of the right side.

The solution to this equation could not be determined.
