Suppose that P(x)=x^5+x^2+1 and Q(x)=x2−2. If r1, r2, r3, r4 and r5 are the five zeroes of P(x), find the value of Q(r1)×Q(r2)×Q(r3)×Q(r4)×Q(r5)

I don't think that's in the scope of MX1... the maximum number of roots questions could go up to should be four (but could someone confirm also)

I hope this helps! :D
Thanks a lot for the help man, I really appreciate it !!!

Your solution makes a lot of sense and is exactly what my math teacher did when he reviewed the question. Thanks once again !!!
