Student Video #1: Unit F. Concept 10

• What is this video about? 

This video goes over how Unit F. Concepts 6 &1 0 on how to find the zeroes of a polynomial to the 4th to 5th degrees. There are descriptions of each step which include using the rational roots theorem, Descartes Rule of Signs, using synthetic division to find zero heroes of the polynomial in problem #6 until its a quadratic, and factoring to get the remaining zeroes of the polynomial.

• What does the viewer need to pay special attention to in order to understand the concept?    

1. Remember that you use synthetic division until your answer row is a quadratic. For this problem, because it is in the 4th degree, you only have to use synthetic division twice CORRECTLY (meaning that the two times you use synthetic division you are left with a Zero Hero!) The video will elaborate more on that.
2. Make sure to note that if the polynomial is not factorable then you will have to use the quadratic formula to find the zeroes (which will most likely be imaginary/complex numbers). However for this problem in particular, it is factorable but if you don't like using the grouping method, you could use the quadratic formula if you wanted to.
