B.O.B. - Muddiest Point

My most difficult experience in this class (so far) was learning how to "complete the square."  When it was taught in class, I didn't quite get it.  I was pretty lost until Mr. Jackson explained #46 in the 2.7 Inverse Functions packet.  I had previously watched the video in which WolframAlpha explained it, but it made absolutely no sense, probably because she didn't give any examples.  When I watch Mr. Jackson do it, there were actually numbers that I could use to view the relationships between 2 variables.  That made it MUCH easier to figure out what the deal was.  The main issue was the (b/2)².  I couldn't figure out the reasoning behind doing this, or where to put this new value in the function, etc.  Now I understand it to the point where I can use it in the future (in class).
