Rational root theorem | Unit 1 and 2 VCE Maths Methods

This video is aimed at students studying Unit 1 and 2 of VCE Mathematical Methods. This video is part of a topic on Polynomial functions In this video we introduce the rational-root theorem, which is needed if we are unable to identify an integer root using the factor theorem. My class uses the Cambridge Senior Mathematics textbook for Units 1 and 2 Mathematical Methods for the Australian Curriculum / VCE and the TI Nspire CAS CX II handheld.
