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 don't have a text book and I can't find my class notes
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...
