Answer 1

Answer 2

That^ is indeed the discriminant for a quadratic function


When you go above just the normal quadratic he discriminant is always a polynomial function of the coefficient

So for example, a cubic equation will have a discriminant

\[\Large b^2c^2 - 4ac^3 - 4b^3d - 27a^2d^2 + 18abcd\]

Answer 3

oh okay, thnks.

Answer 4

No problem!
