SV #1: Unit F Concept 10- Finding all real and imaginary zeroes of a polynomial
In this student video, I was given a polynomails and I was suppose to find the complete factorization and all the zeroes. This problem is about getting a given polynomaial of 4th or 5th degree and finding all the zeroes. In this probelm we had to deal with real and complez First I had to find all the p's and q's. Then I did p/q to find the possible real/rational zeroes. After that I used Descartes Rule of Sign with f(x) and f(-x)to find out how many possible (+) real zeroes there was and how many possible (-) real zeroes there was. Then I used synthetic division to get my polynomail into a quadratic. Lastly I used the quadratic formaula to get the reamainig zeroes.
The trickest part of this problem were the complex numbers. Using the quadratic can be hard if you mess up. If you mess up once, it can ruin your whole answer. With the complex numbers, you have to remember to simplify your answer all the way or it will be counted wrong. Other than that, Unit F Concept 10 is easy if you remember all the steps.

SP #2: Unit E Concept 7: Graphing polynomials and identifying all key parts
This student problem I made my own example of a polynomail that I graphed.I included the x-int which were (-2,0), (5,0) and (-3,0). I also included the y-int which was (0,-60). The zeroes were -2M2 (bounce), 5M1(through), and -3M1(through). The steps I needed to do to complete my problem was first make up my own factored equation. After I did that, I was able to get the whole eqaution by factoring them together. Then I was able to find the end behavior, the x-int with multiplicities, the y-int, and was able to graph it. Even though it was a huge y-int i made the y-axis going by tens and the x-axis by ones.
The trickest part of this problem is making sure you only cross the x-axis at the gates. If you do not graph it correctly you do not get it right. You can only go through the x-axis at the gates and makes sure it is with the right multplicity (through, bounce, and curve). Other than the graphing part everything else is pretty easy.
