SV 1 Unit F Concept 10 4th and 5th Degree Polynomials
For this problem, we are focusing on finding the real and complex zeroes of a 4th degree polynomial. To solve for this polynomial, we will be using all the concepts that we learned throughout unit F to help find the zeroes of this polynomial. This video demonstrates how to find all the zeroes for the polynomial as well has helping you get a better understanding of the concept.
The viewer needs to pay special attention to the Descartes rule of signs because many people have issues when dealing with this part of the polynomial. They should also pay attention to how the problem is solved by using synthetic division to get the polynomial to a binomial. Once reached to the binomial, the equation becomes very easy to solve by either using the quadratic formula or grouping method. It is important to remember that there is a possibility of imaginary or irrational zeroes.
