B.O.B. #2

The muddiest point that I personally have experienced at this point is the maximum area type of problems. I find them quite difficult to solve as they are formed out of a large amount of equations, some of which don't seem to really get you any where. The fact that we solve for x by solving for the vertex is about the only thing I can do without having to check and recheck the answer key to make sure everything looks correct.
