X^{2} +
X
+ = 0

X_{1} = Answer

X_{2} = Answer

If the answer is NaN (Not a Number). It means the answer is imaginary number.

( X + )
( X + ) = 0

factors of quadratic equation

First root =
X_{1} =

Imaginary answer if NaN

X_{1} = b + i

Second root = X_{2} =

Imaginary answer if NaN

X_{2} = b - i

X_{1} = ( b + Square Root ( b^{2} - 4 a * c ) ) / 2 * a

X_{1} = ( b + Square Root ( ) ) /
=

X_{2} = ( b - Square Root ( b^{2} - 4 a * c ) ) / 2 * a

X_{2} = ( b - Square Root ( ) ) /
=
