Step-by-step explanation:
As we know about the discriminant value i.e.
if we have given a quadratic equation :
then,
discriminant value will be
There are 3 properties regarding discriminant value as follows:
So, here we need a zero real number solutions i.e. there does not exists any real number.
So,
Hence, Option'a' is correct.
