Question

If the discriminant of a quadratic equation is 4, which statement describes the roots?

-2 complex roots
-2 real roots
-1 real root
-1 complex root
PLEASE HELP

Answer 1

Statement which describes the roots is:

2 real roots

Explanation:

If the discriminant D of a quadratic equation follows:

D=0 then there are 2 equal real roots or 1 real root

D>0 then there are 2 unequal real roots

and if D<0 then there are 2 complex roots

Here, we are given the discriminant of a quadratic equation is 4

i.e. D=4 >0

So, it means quadratic equation has 2 real roots

Hence, statement which describes the roots is:

2 real roots

Hence, statement which describes the roots is:

2 real roots

Answer 2

The best and the correct answer among the choices provided by the question is the second choice.

An equation can have 2 real roots if the discriminant is 4.
