Ok, if I integrate each of them separately, I believe that the series diverge. And I know that the bottom needs to increase than for the top for the integral converge. thanks for your hints!

Find c ∈ IR, like ∫∞ ( 2x - c ) dx is convergent 0 X^2 +1 2x+1 I need your help because I was trying to resolve the problem, but I couldn't, is difficult for me. Please help me!
