Best ResponseYou've already chosen the best response.0\[\int\limits\limits\limits\limits_{}^{}\frac{ x ^{2}+x+2 }{ x ^{2}1 } dx \]

Best ResponseYou've already chosen the best response.0Whenever I solve this I always get: A= 1 B= 2 then \[\int\limits\limits_{}^{} \frac{ 1 }{ x+1 } + \frac{ 2 }{ x1 } dx\] after substituting A and B and checking if I will still get the original integral, it's not the same anymore. How can I solve this integral?

Best ResponseYou've already chosen the best response.1did you do the long division first before u partial frac'ed it? u'll lose a few terms if you didn't do that.

Best ResponseYou've already chosen the best response.0No. I immediately used partial fraction. Then I need to divide this first?

Best ResponseYou've already chosen the best response.1yes. you'll miss a few terms if u didn't(faced this problem once in my exam==costed me 5 precious minutes)

Best ResponseYou've already chosen the best response.0Oh. Ok, I'll try dividing it first.

Best ResponseYou've already chosen the best response.0This is a bit embarrassing, but I'm not sure if I got the quotient right. When I divide the two I get the answer of 1 with a remainder of \[\frac{ x+3}{ x ^{2}1 }\]

Best ResponseYou've already chosen the best response.1yeah. then proceed to partial frac it. then, after that you can integrate it.

Best ResponseYou've already chosen the best response.0Just to be clear, after dividing I will get this? \[\int\limits_{}^{} \frac{ x+3 }{ x ^{2}1 }\] I will then proceed to partial fraction then integrate? Thanks!

Best ResponseYou've already chosen the best response.1\(\int (1+\frac{x+3}{x^2 1})dx \) .<this yup. You're welcome :)
