*i think it is b^2-4ac but i am not sure

Answer 1

It'd be quick and easy to do an Internet search for "discriminant." Why not do such a search now? This concept ("discriminant") is important enough for you to make the effort to look it up and try to understand its purpose.

Answer 2

i know its purpose- to find the number of solutions to a quadratic equation
WHAT I NEED TO KNOW Is what you use to find it

Answer 3

The discriminant tells you what kind of zeroes the quadratic function will have.

Answer 4

If the discriminant is positive, it'll have 2 real roots. D = 0, one real root, D < 0, no real roots.

Answer 5

so what formula do you use to find it?

Answer 6

It's the one in your original post.

Answer 7
