Basically, the problem gives me a wave function and asks me to find the wave function in momentum space. It then asks me to find the expected value. Namely <p> and <p^2>. The problem is, when I try to calculate <p> it blows up to infinity. What am I doing wrong? Here is my work...

Check the step where you complete the square...I think you may have made an error at that point.

Of course! Thank you very much. I guess that is a sign I should stop doing work and sleep. :]
