    Can I assume that you really mean
    [itex]\int\left\left[(u/\left(5u+11\right)\right]du[/itex]?
    Integrals don't make much sense without the differential! (And I want to be certain that you mean u as the variable of integration!)

    Have you considered the substitution x= 5u+ 11? (And having that "du" in the original integral will remind you that you need to use du= dx/5.) That will make the denominator very easy! Of course, u= (x-11)/5 but that's in the numerator and is no problem.
