The discriminant for the equation
Ax+By+C=0
is sqrt(B²-4AC)

If the quantity under the square-root sign is >0, there are two real roots. If it is zero, there is one real root, in fact, two coincident real roots. If it is negative, the equation has two imaginary roots.

Post you answer if you need a check.
