partial fractions? or x= log y substitution or how ??

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

But you do have a function squared. wHICH You can expand to get a ^2x

what would i take in numerator ?? if it were (x+1)^2, i would have taken A/(x+1) +B/(x+1)^2 ...

Yeah, or Ax+B for numerator if you expand it.

I 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

But it looks like partial should work.

the answer suggested me partial, but how is the question....

Right but what are the steps to derive this?

then partial fractions...
