I enjoyed this. It is well done. I think most student could follow it. However, there is one false statement in the video. At 1:30 he writes an equation that says that 9/4 = (9/4)^2. That is obviously not true. Most students will realize that in the attempt to save time and space of writing the 9/4 over again before squaring it, he just continued the problem. Yet this approach does not teach the integrity of the equals sign: that one side has the same value as the other side.
