Best ResponseYou've already chosen the best response.5for partial fractions, there should be linear expression, 1+xe^x is not linear....

Best ResponseYou've already chosen the best response.0But you do have a function squared. wHICH You can expand to get a ^2x

Best ResponseYou've already chosen the best response.5what would i take in numerator ?? if it were (x+1)^2, i would have taken A/(x+1) +B/(x+1)^2 ...

Best ResponseYou've already chosen the best response.0Yeah, or Ax+B for numerator if you expand it.

Best ResponseYou've already chosen the best response.0I think you can use Ax+B w/o expanding. haha. I'm just making guesses now. I don't have a pen within a 12 inch radius Lol

Best ResponseYou've already chosen the best response.0But it looks like partial should work.

Best ResponseYou've already chosen the best response.5\(\huge \int \frac{e^x(x+1)}{x.e^x(1+xe^x)^2}dx=\int \frac{dy}{y^2(y1)}\)
