i really dont know
\[x = \frac{ -b \pm \sqrt{b^{2} - 4ac} }{ 2a }\] the discriminant is \[\sqrt{b^{2} - 4ac}\] because it can be used to discriminate between solutions.
oh. that's relatively simple then. Here's a hint: ax^2-bx-c=0 (minus sign is just there; it doesn't matter). works in conjunction with binarymimic's comment.
The discriminant is actually a bit simpler, it's the radicand of that expression: \(b^2 - 4ac\) It is useful because the sign on it tells us whether there is a positive number or negative number under the radical. In the case of a positive, we have two real roots. In the case of a negative, we have two imaginary / complex roots. If we have 0, then we have a single root that is repeated. ((-b +- 0) / (2a))
Actually, the discriminant is just \(b^2 - 4ac\).
