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


         Need help understanding Unit F Concept 10? Well here is a video I made that will hopefully help you better understand this concept. This problem that I have chosen will help you further understand in how to find the zeroes, real and complex numbers. As well will it review some things like synthetic division and Decrates' rule.
          Please pay attention in how I get the p's and q's as well in the zeroes it is supposed to say (4x-11-rad177/4) and (4x-11+rad177/4). Sorry I forgot to go over and make sure that it had those numbers in front of the x.

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

Before looking down below for the extra help or wanting to know the answers please try to solve this problem by yourself:
x^4+x^3-16x^2+20x

In this problem you will be reviewing in how to solve a polynomial expression by finding the zeroes and the multiplicity's found and how to graph them without using a calculator. With the picture below you will be able to see the way to find the zeroes and multiplicities as well as graphing them out.

Please pay special attention in how to find the multiplicities and in how they will affect your graph. As well be sure to (if wanted) to plug back in the zeroes found to see if they are correct and to be sure that they make sense on the graph. Be sure to label out the graph as you put the points on there.

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

If you will please try to solve/transform this equation on your own first and if you can't then please look at the pictures below for help ^-^ :
y=6x^2+12x+10

     This problem is about how to solve a regular polynomial and transform it into a parent-function and be able to graph it all out and find all of the components for the vertex, y-intercept, and axis. As well to be able to fully understand how to create these parent-functions.
     Please pay special attention to how to get the vertex, y-intercept, and axis. As well pay attention to the x-intercepts because when you are going to solve  it, you will see it's an IMAGINARY NUMBERS and won't be able to fully graph it out.
