By inspection on 4(n + 1) = (2n-6)!, n = 5 works.

1.) Never make an effort to come up with a useful thread title. $\checkmark$

2.) Never show work or effort that would be useful to actually give help. $\checkmark$

3.) Never alter 1.) and 2.) despite numerous advisories. $\checkmark$

Write in this form : $\displaystyle 4\Gamma(n+2)=\Gamma(n+1)\Gamma(2n-5)$
Now try to solve.

Who people decide to help is up to them...in my mind, the complete and utter laziness here lies solely with mared.

To me, "enabler" is a word invented by the guilty to shift the blame from where it rightly belongs.

Please answer me. If no one replied to mared, then would it not discourage the existence of his further "complete and utter laziness" of posts.

He is a panhandler.

Why did you bother making the points in post # 3? You just stated facts that he doesn't care about.

I made my post primarily to point out (again) to mared that his posting style is extremely deficient.

I did so publicly because I have grave doubts that he/she would take the time to read a PM or VM.

Also, as a moderator, one gets tired of having to come repetitively along behind the same lazy user to fix their useless titles. I have mentioned the "title issue" more than once in the past to mared, but it falls on deaf ears.

So, please indulge my venting of frustration.
Thanks from topsquark

Been there, done that. Much sympathy offered.

I admire your patience. On the board I'm a mod, he would probably have been banned already.
