0.4444444444 + 0.01234567901x + x2 = 0

Move the constant term to the right:

Add '-0.4444444444' to each side of the equation.
0.4444444444 + 0.01234567901x + -0.4444444444 + x2 = 0 + -0.4444444444

Reorder the terms:
0.4444444444 + -0.4444444444 + 0.01234567901x + x2 = 0 + -0.4444444444

Combine like terms: 0.4444444444 + -0.4444444444 = 0.0000000000
0.0000000000 + 0.01234567901x + x2 = 0 + -0.4444444444
0.01234567901x + x2 = 0 + -0.4444444444

Combine like terms: 0 + -0.4444444444 = -0.4444444444
0.01234567901x + x2 = -0.4444444444

The x term is x.  Take half its coefficient (0.5).
Square it (0.25) and add it to both sides.

Add '0.25' to each side of the equation.
0.01234567901x + 0.25 + x2 = -0.4444444444 + 0.25

Reorder the terms:
0.25 + 0.01234567901x + x2 = -0.4444444444 + 0.25

Combine like terms: -0.4444444444 + 0.25 = -0.1944444444
0.25 + 0.01234567901x + x2 = -0.1944444444

Factor a perfect square on the left side:
(x + 0.5)(x + 0.5) = -0.1944444444

Can't calculate square root of the right side.

The solution to this equation could not be determined.
