SV 5 Unit J Concept 3-4: Matrices
Some things to notice is that to solve a matrices, you need to be able to get the triangle 0's and the 1's staircase. It is possible to use guess and check method, but that would take too long to do. Also, notice that it didn't take very long to solve because of the Gauss-elimination method which made it possible in 4 solutions. Also, remember to highlight the steps are you are doing so you don't get confused when doing a problem and make a mistake.

SV 4 Unit I Concept 2: Logs in Graphs
The important thing to look out for in this video would be how to solve for the x-intercepts and y-intercepts. These parts are the most challenging for students because they usually get messed up on these parts. Remembering the asymptote also helps figure out which points to use because of the restrictions the asymptote puts on the graph. All of these things should be watched for during the video so students don't get mixed up on accident or anything. Thanks!

SV 3: Unit H Concept 7: Finding Logs with Approximations
Things to look out for in this video are to remember the hidden clues because they are super helpful and to remember to correctly use either multiply/division and adding/subtraction symbols so you don't get confused when you write the logs out. Other things to look out for are how the exponent is written in condensed and expanded logs. Anyways, thanks for watching my video guys and have a great day.

SV 2: Unit G Concept 1-7 Rational Functions
For this video, I teach you the steps and guides on how to solve rational functions. This helps determine how the graph comes out as well as other things that are useful for your math class. By solving this problem you will learn how to overcome your fears in math and become a pro at it.
Some things you should notice when watching this video is the awkwardness that I face in video. Also at the end of the video, the graphing part, I was dying so excuse the awkward silence. However, you should pay attention to how the work is done so that you can learn more and be able to do well on the test.
Also do not mind the graph from the first video, i made a silly mistake so just watch the graph from the 2nd video to see how it is supposed to look like when you are done. The vert asymptote is x=-6 and the slant asymptote is x=x. Thanks for watching!

SV 1 Unit F Concept 10 4th and 5th Degree Polynomials
For this problem, we are focusing on finding the real and complex zeroes of a 4th degree polynomial. To solve for this polynomial, we will be using all the concepts that we learned throughout unit F to help find the zeroes of this polynomial. This video demonstrates how to find all the zeroes for the polynomial as well has helping you get a better understanding of the concept.
The viewer needs to pay special attention to the Descartes rule of signs because many people have issues when dealing with this part of the polynomial. They should also pay attention to how the problem is solved by using synthetic division to get the polynomial to a binomial. Once reached to the binomial, the equation becomes very easy to solve by either using the quadratic formula or grouping method. It is important to remember that there is a possibility of imaginary or irrational zeroes.
