Completing the square, the easy way

Thanks for the positive feedback my lessons have been receiving from the forum.
Completing the square is often a very confusing topic, and the essence of the method is not always easy to grasp. Do you know that you can solve by completing the square with just a little more than a simple drawing? In the lesson below I am going to show you how.
Let me know if something is not clear.

Are you going to show the analogous way of computing the cubic equation, but using a 3D cube instead?

That would be interesting but too complicated, especially for my target audience.

Math Focus: Mainly analysis and algebra
I think that, having started with a good idea, you then needlessly over-complicate it yourself
