Hello. I seem to be having a little trouble with this problem regarding quartics so if you could assist me, it would be greatly appreciated:

============================

A polynomial with real coefficients and two integer zeroes p and q is given as:



has a complex zeroes and

Using p and q, write another expression for a real quadratic factor of and using this, list the possible values of whereby , and are the zeroes of

So far, using sum and product, I wrote it as a quadratic factor:



That means the quartic can be written as (using the real and complex factor):



Is this right so far?

Given , show that there's only one possible value for and hence, find all the zeroes of

============================

If you could help me out here, it would be greatly appreciated.

Thank you.

I think more information is needed.

This was all the information I was provided with . You mean there's no other way to find the zeroes of the quartic?

Thanks though. Your help was definitely appreciated.

Are you meant to get them in terms of a, b and c?

It doesn't state but I guess that's what you're supposed to do.
