Best ResponseYou've already chosen the best response.1if you mean \(\large \int \frac{3}{(x+1)} + \frac{2x}{(x^2+9)} \ dx \) looks right, if you added an integration constant maybe you need to manipulate a bit to please the software?

Best ResponseYou've already chosen the best response.0Well the software returns an extra set of parentheses, making the answer\[(\log(x^2+9))3\log(x+1)\] It seems like it should be right, but it just won't accept it

Best ResponseYou've already chosen the best response.1hi @RunawayGalaxy or you can write \(ln \frac{1}{x^2 + 9} + ln \frac {1}{(x+1)^3} + C\) dunno, looks like a glitch, sure a human would be very happy with your work, webwork is presumably some kinda online thing....

Best ResponseYou've already chosen the best response.1well, i stuffed it into Wolfram to eliminate "completely losing the plot" risk... and the Wolf agrees with you! http://www.wolframalpha.com/input/?i=+%5Cint+%5Cfrac%7B3%7D%7B%28x%2B1%29%7D+%2B+%5Cfrac%7B2x%7D%7B%28x%5E2%2B9%29%7D+++dx
