I am putting together a collection of what I see as bad habits that I see as a teacher. I have not found any other resource that seems to show this so I thought that it would be a good idea to make a start.

What I would encourage you to do is take a sheet of paper and answer the question as if you were doing it in an exam then check the video. See if you have developed some bad habits. I have tried to make the question as short and as easy as possible to demonstrate a point.

Expand and simplify (x+2)(x-3)
