Verified Answer :

Answer:

The answer is A,C,D

Step-by-step explanation:

Answer:

The correct options are A, C and D.

Step-by-step explanation:

We know that,

The quadratic formula for the quadratic equation \(ax^2+bx+c=0\) is \(x=\frac{-b\pm \sqrt{b^2-4ac}}{2a}\).

Now, we have,

The discriminant is \(D=b^2-4ac\).

So, from the options, we get that,

The true statements for the discriminant are,

A: The discriminant is \(D=b^2-4ac\) in the quadratic formula.

C: The discriminant is the radicand of the quadratic formula.

D: The discriminant is the value under the radical in the quadratic formula.
