Discriminant is part of the solution. Just considering it tells you the types of solutions that you have.
There are three possibilities:
1. 2 real roots,
2. 2 complex roots,
3. 1 repeated real root.

If the discriminant is bigger than 0 you have 2 locatable 0 crossings. If it equals 0 there will be in elementary terms one0 factor, and it will likely be a optimal or a minimum. If the discriminant is below 0 there will be no 0 crossings for the graph. 0 crossings meaning factors the place the graph crosses the x-axis.

The discriminant is the portion under the radical in the quadratic formula. It is b^2-4ac
If is is positive the euation has 2 real roots
If it is negative the equation has 2 immaginary roots
If it is zero the equation has a double root.All that means is that there is one answer.
