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


To watch my video press here.


This video is about showing how to solve an equation to find all the zeroes that it contains. In this problem you will be able to see how to list the possible zeroes, use Descartes Rule of Signs to find the number of positive and negative zeroes, as well as using the quadratic formula to find some zeroes after you have used synthetic division to evaluate for some zeroes.

When watching this video, be sure to follow the steps. These steps include finding the p's and q's, using the ruler of signs, and making sure to use synthetic division. Make sure your math calculations are correct so that you will be able to get all the zeroes needed for the problem.

SP#2: Unit E Concept 7 - Graphing a polynomial and identifying all key parts


In this problem, we are trying to sketch a graph about polynomials by finding its x-intercept, y-intercept, zeroes, and end behavior. You are first given a polynomial equation and you must solve for the needed information to graph your problem.

In order to solve this problem, you must be able to distinguish how a graph will look like depending on the polynomials leading coefficient and its degree. You must also be able to factor an equation so that you can find the zeroes and eventually be able to plot them on your graph.

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


In this problem, we must be able to create our own quadratic ins standard form. We must then put it in vertex form so that we can graph it if it is possible. Apart from that, we must show how to find the vertex, y-intercept, axis, and x-intercepts.

To understand how to solve these problems, the viewer must observe how to complete the square in order to make the problem in vertex form. They must also see how to distinguish each letter such as "h or k" to use them well graphing.
