Algebra-2

To find a quartic function with only real zeros at and , we can analyze the given options.

 

Analysis of Options:

A. :

   - Real Zeros: The factors and give zeros and . However, the factor gives a zero at , which is not required.

   - Total Zeros: This function has an additional zero that is not needed.

   - Conclusion: This function does not meet the requirement.

 

B. :

   - Real Zeros: The factors and give zeros and , which are not the required zeros.

   - Total Zeros: This function does not have the required zeros and
