Question

Use the Discriminant to classify the cocnic section X^2+y^2-6x+8y-24=0?

Answer 1

That's a new one on me. That is the equation of a circle. I didn't know circles had discriminants.

Answer 2

So I learned something. A = 1, B = 0, C = 1 B^2-4AC= -4
If the discriminant is negative, the graph is a circle, an ellipse, a point or has no graph.
