So the short end of this video is, can you prove that the algebra in it is flawed? I'll go ahead and write the answer below...

This is a fun little trick to fool those that may be mathematically challenged.

The flaw is: Suppose a=b=0 and run through the steps. The step which shows "divide through by (a-b)", if a-b=0 it is an illegal mathematical method to divide through by 0.
