comment How to compute $\int \frac{x}{(x^2-4x+8)^2} dx$?
@anorton Let's keep it civil, shall we? All what I'm saying is that the answers presented here are merely special cases of a general solution we already have on this site. The reason we have a generalized answer is precisely to avoid a proliferation of special cases that don't add value. Given how straightforward it is to apply the general solution to this case, I doubt that there is value in waiting for new methods.

@anorton If there is a method not mentioned in the general answer, it should be added there.

comment How to compute $\int \frac{x}{(x^2-4x+8)^2} dx$?
@anorton Do you have an answer to the OP's second question that isn't a subset of the generalized answered posted by Peter? We have generalized answers for a reason.

@amWhy The OP asked for a more general case. The answers below don't answer that. I think it is a duplicate.

Your English is OK. Where does this question come from? Do you have any thoughts on how to approach it?

Did you try using the fundamental theorem of Calculus?

comment Can the boundary of a subset be open?
While this is true, the boundary can be open and closed at the same time. These are not mutually exclusive properties.

comment Programming string in math
@jcubic I don't understand the question. What do you mean by language theory? If you're looking for the analogue of string in formal languages, then it's called a word.

comment Programming string in math
Strings are called "words" in formal languages. Check out Wikipedia.

Please don't use \displaystyle in titles; it uses too much vertical space on the homepage. Thanks

comment The set of points where two continuous functions agree is closed.
I think it was fine. I just got confused for a second and thought we were talking about a union.

comment If $p:E \to B$ is a covering map, and if $E$ is compact, prove that $p^{-1}(b) $ is finite for all $b \in B$.
This assumes that singletons are closed, no?

comment Show that a star convex set $X \subset \mathbb{R^n}$ is simply connected.
Since constant maps are continuous, every space retracts to a point. This doesn't help much. What you should be looking for is a deformation retract.
