Please circle the name of your TA:
Nathan Panike I Keya Zhu Show all your work in order to receive credit. A correct answer without any work
will receive 0 credit. Partial credit will be given ONLY for results that are correct
and relevant to the problem. Please write your answers neatly. Good luck! _ 1. (10 points) Let f(X) = X4 +2X3 +X2 +8X — 12. Given that a: = 22' is a zero
