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

This is my student video number one and we are trying to find the zeroes of the given equation. In the video I will explain how to find your ps and qs. You will also get to use Descartes rule of signs. To find the zeroes is a long process but if you learn the steps they are fairly easy.
Try the problem I had some trouble with it and tried to find the answer I was given but found something close to it. Try it for yourself and make sure to take your time. My problem number is 19 and make sure you take your time so you could get the right answer.

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

This is the Student Problem #2. This question has to do with graphing polynomials and finding their point of declination and inclination. To help you out, there are going to be four zeros. You can determine this by the degree of the first x in the equation, you can also determine the end behavior of the graph. Look at the degree and leading coefficient.

For this problem make sure you know how to factor and find the zeros and use multiplicities. In the end your graph and work should look like mine. Good luck and try your best

SP#1: Unit E: Concept 1: Identifying X-Intercepts, Identifying Y-Intercepts, Vertex (max and min), axis of quadratics and graphing them, Quadratics in standard form



This picture shows how to find the different parts of a quadratic function using standard form, and then having to graph them. This picture demonstrates how to find the parent function equation, vertex, y-intercept, the axis of symmetry, and the x-intercepts.

Notice that in the graph the quadratic is facing upwards, this is because the a value is positive, if the a value were to be negative then the quadratic would be facing downward. Use (h,k) to find the vertex of the quadratic. When you find the X-intercepts make sure to plug them into your calculator. Have Fun!:)
