Hi all,(adsbygoogle = window.adsbygoogle || []).push({});

can you help me to compute these integrals?

[tex]\int \frac{x \sqrt{a x+b+x^2}}{d^2+x^2} \, dx[/tex]

[tex]\int \frac{x}{\left(d^2+x^2\right) \sqrt{a x+b+x^2}} \, dx[/tex]

a,b and d are real and positive.

I tried with Mathematica, but the results involve logarithmic functions with complex argument whereas I need a solution in the real domain.

Thank you to all in advance.
