Done by parts integral and simplify

SUMMARY

The integral of the function (x^2)(e^x)dx/((x+2)^2) can be effectively solved using integration by parts. The discussion highlights the choice of u as (x^2)(e^x) and dv as 1/((x+2)^2). By differentiating u to find du and integrating dv to find v, the integral can be expressed as u*v - integral(v*du), leading to a simplified solution. This method proves to be efficient for the given integral.

i have to integrate the next:

(x^2)(e^x)dx/((x+2)^2)

It should be done by parts.
How I can simplify it?

Is (4x+4) (e^x) dx/(x+2)^2 easier to be integrated?

the easiest way to do this is by parts.
let u=(x^2)(e^x)
let dv = 1/(x+2)^2

get du by differentiating u by x
get v by integrating dv in terms of x

then write out u*v - integral(v*du)
the integral simplifies pretty nicely.
 
Thank You a lot!
