Great proof but a small critique: it isn't helping how you justify using the expression in 3:38 by simply saying that it is useful later. That isn't helping me understand why you are using it and how you are using it. How did you think of coming up with the expression? What was the reasoning? Please go deeper into this. Thank you.
Thank you ! A simple proof for such a useful inequality!

Now you just have to notice that this sum is a square so it's positive ET VOILA!!!! It could have fit into one clip, could it not?
thank you!!
