Hi Kino! Welcome to PF!

Well, basically it's right (except for the "28" of course ) …

you just need to replace (x+1) by something else …

then you can check that it's right in exactly the same way that you checked that (x+1) was wrong.

(btw, what did this have to do with "greatest integer"? )
 P: 2 I meant the parentesis are the integers signs but i didnt now how to put them... But today i may get the answer so i'll publish it
