I have a problem regarding on how I approach the attached integral.

Can you guys guide me on how I should approach this? Thank you very much

I would complete the square for x^2 + 8x + 25.

Thank you very much. I hesitated doing that at first. But now, it seems like the best method there is.

Getting u^2 + a^2 to any power is almost never a bad idea.
