HELP ASAP PLZ!!!
Zidan is using the Rational Root Theorem to help find the roots of a 5th degree polynomial. He has discovered five roots and still has 4 to test. What is his next best step? He should test the remaining 4 roots. He should use the Factor Theorem to find the remaining polynomial roots. He can stop testing because he has found all the roots. He needs to pick one of the roots and use the quadratic formula to test it.
