It's a pity you didn't do it with algebraic manipulation. Proving this case with proof table is rather useless for this course, since this method is very straightforward and pretty well served in the Velleman's book, you mentioned. While some practice with formidable expressions would be nice.
Knowing how to approach it from either truth tables or algebraic manipulations is valuable. This particular video uses the truth table approach, other videos on the playlist use algebraic manipulation. Thanks for watching.
