See video and instructions here.
This video will go over how to find all the zeroes, real and imaginary, from a given polynomial of a fourth or fifth degree. I will also go over previous concepts used to find the possible real zeroes as well as how many possible positive and negative zeroes there are going to be. We will also be reviewing the quadratic formula as well as synthetic division.
Be sure to pay attention to how many possible positive and negative zeroes there will be because in some cases there maybe be no positive and only negative or vice-versa. Also make sure to pay attention to the synthetic division because it can get confusing at times and sometime multiply or subtract incorrectly. Lastly, make sure you use the quadratic formula correctly or else your zero will be incorrect.
