Solving cubic equations | 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 solve cubic equations using simple rearrangement where possible, but failing that, we use factorisation and the null factor law. This video makes use of the factorisation skills established in the previous videos.
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.
