The question is asking me to do ∫∞04x(1+x)5dx
My question is, is there any way to do this without partial fractions. If there is a formula for equations of this type, I will gladly memorize it, I just don't think I'll have time to partial fraction expand a question like this on the P exam.
Answer
Let u=1+x, then du=dx and so your integral is now
∫∞u=14(u−1)u−5du=4∫∞1(u−4−u−5)du=13
