I am confuse about what is discriminant and when do you use it?
Can anyone give me a good definition of it and when to use it?

I used google and got this "The Discriminant of an equation gives an idea of the number of roots and the nature of roots of the equation" but I am confuse about this definition.

I was hoping for someone to give me a good answer about discrimininant that could be easy for me to understand...

Disappointing and surprising that Google only gave a single hit. Otherwise you could have read through many more of them and found one that explained it in a way that you understood.

Well, do you think you could explain to me in a way a newbie high schooler could understand?

Once you have made a genuine effort and exhausted the possibilities mentioned in this thread, someone might. Perhaps it's also worth trying to find your class notes.
