Made the problem nice and neat with Word Tools: I have a midterm on monday and I can SOLVE ANY problem and have memorized all common trig integrals. This is the only thing I can't do and its frustrating me and I forgot to ask my professor in office hours. Ive done every homework assignment twice, im intent on acing this class, and this is a harder problem on the review for the test.

I have tried all sorts of substitutions, even completeing the square and then using trig identities, Ive been working non stop on this problem for 40 minutes..

Could someone please help me, thank you in advance
