# C1 question on terminology Watch

1. So, I was just thinking to myself, you know, as you do: if a question states an equation has real roots does that mean the discriminant is
or does it mean

It doesn't specify that it has equal / different real roots so it should be

Right?

If it doesn't specify distinct roots then when it says a quadratic has real roots then the discriminant is since real and equal roots are still real roots.

as if it is equal to zero it still has one root, which is still a real root

4. Well yes, since equal roots would mean the discriminate is equal to zero.
