Does anyone feel like this question is worth keeping?

It looks like a straight up PSQ to me, but according to a review audit, it shouldn't be closed for lacking context.

I feel like it's worth keeping. I like it :D

Aside from the fact that it is an upper-division homework problem, rather than a calculus homework problem, how is it not a PSQ?

I didn't say it wasn't. I said I like it :P

Okay, but "I like it" doesn't convince me that it is worth keeping.

If the standard is that problem statement questions are poor quality questions and should be closed, how does one justify keeping that question open?

Moreover, even if we can't agree as to whether or not the question should be kept open, can we at least agree that it is pretty marginal, and is not a good audit question?

Awwwwwwww, but Xander. :c You don't care that I like it?

Yeah, it's a bad audit question though

But we've talked about this: I'm personally down with keeping PSQ/exercises on the site so long as I think they present value to future readers of the site. When studying for the Complex Analysis Qual, I would've been happy to find such sample "Rouche's Theorem" exercises to practice on this site.

So I mean, I'd argue to keep it, but I know $>5$ people are holding that same standard as you, so it'll probably get closed and deleted.

It's a mild shame to lose all the work dan_fulea put into responding to it

I'm not gonna vote to close it, since I think that the answer is pretty enlightening

and while I don't generally think that good answers save bad questions, that answer could serve as a duplicate target for a lot of tricky Rouche's theorem problems

but in the review queue, answers are invisible

Well, since (I suppose) the goal is to not have PSQs visible on the site do discourage the culture of asking PSQs, would this be a good question to "ask better" and then request a merger?

Perhaps. Though I am not sure what "better" would be. Perhaps incorporating the first paragraph of the answer into the question (i.e. note that, numerically, the two "bad" solutions are only barely bad).

At least the other answerer tried to find another polynomial and apply Roche. Do no other "obvious" choices of other polynomial work? I think that's enough context: here's a few natural guesses at a polynomial to try Rouche's theorem with, but they don't work. Can this be done with Rouche's theorem? How do you see which polynomial will work in this tough case?

I'm gonna edit it and bump it (the title sucks at least). It would be nice if some Complex Analysis Wizard saw it to confirm that it's not so straight-forward.

https://math.stackexchange.com/review/close/1015074 This question is a fairly straight-forward "problem statement question" that I voted to close as "Lacking Context." I think that the level of the material (advanced undergraduate or introductory graduate level complex analysis) coupled with th...

Q: What is the expansion for $\frac{1}{1+x+x^{2}}$?

What is the expansion for $\frac{1}{1+x+x^{2}}$? I know expansion for $$\begin{align}&(1+x)^{-1}=1-x+x^{2}-x^{3}+\dots\\ &(1+x)^{-2}=1+(-2)x+(-2)\frac{-3}{2!}+(-2)(-3)\frac{-4}{3!}+\dots\\ &(1+x^{2})^{-1}=1-x^{2}+x^{4}-x^{6}+\dots\end{align}.$$ But for $\frac{1}{1+x+x^{2}}$ I got problem. Can so...

@LeakyNun This is worse.

@user21820 I originally found like 8 duplicates

my comments were deleted

are the questions marked as duplicates?

@LeakyNun Well the one you linked is marked as duplicate of 3 others.

By "worse" I meant "with less effort/context shown".

Leaky Nun

have the other questions been marked as duplicates, including the questions in my comments that were deleted?

@MikePierce The standard way to solve that problem is for people who want to keep the content (such as the answerer or you) to post a (far) better question. If you are the answerer, it is especially worthwhile if you can generalize the question, and you can easily copy over the content. If you are not the answerer, you can still ask a moderator to move the good answer[s] over. I'm sure this has been done >5 times before.

@LeakyNun I have no idea. I wasn't around to see them.
