integral of  [ x*(e^x)]  / (x+1) ² dx
----------------------------------------------

-----------------------------------------------
add and subtract a 1 in the numerator to get (x+1)
divide term by term,  to get (e^x) [f(x)+f '(x)] form
split into two integrals
 integrate one of the them  in a proper way  using
by parts rule to cut off the remaining integral
answer and  some steps are given below
