I'm trying to solve an indefinite integral problem using my TI Nspire.  There are some problems I can solve with no issues, however there are other problems that don't seem to give the correct answer.  I believe this is because I'm entering the problem wrong into the calculator.  For example, shows the problem and the correct answer.  When I try to solve it with the TI Nspire I get this, Completely different answer.  What is the proper way to enter this problem into the calculator?

Thanks for you help!
