Wow, thanks so much. That explains a lot about what I was doing wrong. I now understand that the factoring and simplifying was my problem. Nice work Priscila, thanks again.

I got 96(x-1) by bringing down the two in (x-1)^2, and multiplied it by the 48 next to it. Okay, so maybe that is wrong, but I still don't see how the end result is 72(2x-1)(x-1). Then what do you do with the (x-1)^2? Also, they somehow get (2x-1) from my (4x-1), how is that possible? Do...

I have this problem for homework dealing with second derivatives and graphs. I have no problem finding derivatives usually, but this one is giving me trouble. I cannot figure out how to get the second derivative. I have an idea of what to do, but need some extra guidance. Find f '(x) where...
