Answer:
The discriminant of function is 0. There one distinct real number zero of (repeated roots).
Step-by-step explanation:
We are given the following function in the question:
We have to calculate the discriminant of the function.
Comparing to
We get,
Discriminant is given by:
Putting values, we get,
Thus, the discriminant of function is 0.
Since, the discriminant is zero, the function have repeated real roots. Thus, one distinct real number zero of .
