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

Hi this is Sergio from Period 4, and this is Unit F Concept 10. Okay so the first thing you do is that you wanna find the "p's and the q's" and set the up. The next thing you do is use Descartes's Rule of signs. You will find that the possible (+) zeros are 2 or 0, and the possible (-) zeros are 2 or 0 as well. Now, you wanna use synthetic division to find your Zero Heros (or is it Heroes?). Anyways, after you do this, you will end up with a quadratic. After you get a quadratic, you wanna take out the GCF and then plug your values into the quadratic equation. After you plug it in, you should get your zeros and your fully factored form of the zeros. THANKS FOR WATCHING GUYS!!!!!!!!!!!

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

          This problem deals with graphing a given equation, as well as finding its factored form, its end behavior, its y intercept, and its x- intercepts with the x-intercepts' multiplicities. As you can tell, the end behavior is "even positive", so both ends point upwards (positive infinity).

          Some important information that the reader should have in mind is that since we have multiplicity of "1" for all the x-intercepts, you go THROUGH the x axes. Other than this, everything else seems okay.

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

          This problem deals with trinomials, and trying to graph them by trying to find their separate parts, such as the vertex, y-intercept, the axis of symmetry, and the x-intercepts.  By simplifying the trinomial, we find the parent function function equation. By doing this, we make it easier to graph the trinomial.

          I think the reader should have in mind that we cannot graph imaginary number AT ALL in these graphs. The most important step in these problems is completing the square. We must be able to do this as easily as finding the slope when given two points. Also, we must write that "x=3" for the axis of symmetry, and not just write "3", because it will considered incorrect. THANKS!!!!
