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

In this video you will learn how to find the zeroes of a polynomial. This is an all new concept of finding zeroes using a new method by using the synthetic division. Along with using synthetic division, student will also use the descarte rule of signs and p/q to solve for the zeros. What you need to be careful when solving is to check your work, to make sure that you are dividing correctly. In addition to, negative and positive sign will have a big impact on the answer if it is placed incorrectly.

SP #2: Unit E Concept 7: Graphing Polynomial



The problem is about identifying the end behavior, solving for the factors, and putting it into graphying forms. First you need to factor out the equation. Then decide on the end behavior. Solve for the x intercept and use it to graph.

One thing that you need to pay attention to is the coefficient of the first variable, because it determines your end behavior and how many answer you will get in that equation.

SP #1 Unit E Concept 1: Identifying all parts of quadratics and graphing them

This problem is about identifying the x intercept, y intercept, vertex, and axis of quatratic. The vertex is the (h,k), x intercept is y=0, y intercept is x=0, axis of symmetry is x=h. After finding these, you need to graph it.

To be able to solve and graph it correctly, user needs to pay attention to the negative signs (if any). Also the negative or positive signs in the front of the equation tells whether the graph is up or down. Lastly, the imaginary numbers cannot be plotted.
