Best ResponseYou've already chosen the best response.0All right. Here's the thing. If the discriminant is over 0, it has 2 roots. If it's 0, one root. And below 0, complex roots.

Best ResponseYou've already chosen the best response.0As your discriminant is over 0, it should have 2 roots (x intercepts).

Best ResponseYou've already chosen the best response.0Oh, nevermind. I just did the calculation and it yields 23. So there are no real roots.
