Best ResponseYou've already chosen the best response.0use the determinate..i think its called of the quad formula.... if its 0 only 1 root, if it (+) 2 roots, it its () imaginary roots

Best ResponseYou've already chosen the best response.0roots can be complex and most are... but the only one to concern yourself with are the "real" roots
