Student Videos

What is this video about?
-This video covers a problem from Unit F Concept 10 which is finding all zeroes of a polynomial when the zeroes could be real and/or rational imaginary. The problem we chose was # 6 from the concept 6 and 10 extra problems from the unit F sss packet. In this video, we review the p's and q's, Descartes' rule of signs, using synthetic division, and factoring.

What does the viewer need to pay special attention to in order to understand the concept?
-Look at how many zeroes Descartes' rule says we are supposed to get and then look at how many zeroes we actually get.
-Notice how to use synthetic division again once you did it the first time.





What is this video about?
-This video covers a problem from Unit H Concept 7 which covers how to find logs given approximations. In this video, we review how to expand our clues using the properties of logs.

What does the viewer need to pay special attention to in order to understand the concept?
-Look at how we used the prime factor tree to break down what we were trying to find. Factoring makes doing these problems so much easier.
-Notice how we substituted the variables for the logs once we found the log.
