SV# 1: Unit F Concept 10: Finding all real and imaginary zeroes of a polynomial

           This problem is about polynomials. You are first given the polynomials so you can find the zeros and the factorization of the problem.  To find them you can use some steps to figure them out faster. For example Descartes rules of signs, P's And Q's and synthetic division.
          To understand this video you are suppose to know what P's and Q's are as in how to use them to figure them out. You also have to know how to use Descartes rules of signs. You also have to know how to use the quadratic formula.

SP# 2: Unit E Concept 7 : Graphing polynomials and identifying all key parts

                  This problem is about the End behavior and writing equations of polynomials given zeros and multiplicities. It is also about graphing polynomials  including x-intercepts and y-intercepts. This problem can show you how you can graph the polynomial to match the end behavior.
                  You need to pay attention to the zeros because if you don't get one right they wont match you r end behavior or your end behavior to your zeros. you also need to pay attention to the factoring because if you do it wrong you can end up with less x-intercepts (or zeros). Last thing is that you need to remember to write down your end behavior right because it will maybe end up confusing you when it is time to graph it.

SP#1 : Unit E : Concept 1 : Graphing a quadratic and identifying all key parts

This problem is about the parts of the Graph of a quadratic. The 4 parts of the graph of the quadratic are the vertex , X-intercept(s) , Y-intercept and the axis of symmetry. You also have to write down the parent function equation for this problem.
To understand this problem you have to know hoe to complete the square. you need to know how to complete the square in order for you to find out the parent function equation. you also have to understand that you cant graph a problem that has imaginary numbers.
