Why can't I differentiate this nomal/Guassian distrubution?

Have a look here. I'm assured that differentiating 1, with respect to x, gets you 2. Now 2 is - I think, and correct me if I'm wrong - equivalent to 3. The problem is I can't see how 3 is the result of differentiating 1. What's more, an online solver produces something (that looks) very different. Can someone help me out?
