Dear Jenny, 

Sorry I didn't answer your last letter. If I realised how serious the situation was, I would have written to you straight away. You obviously need my advice. I only wish to be with you now to help you. I think it's about time you left your job and started to look for a new one. If your boss insists on treating you so unfairly, then you have very little choice. You say that you'd rather have a job you hate than no job at all, but is that really true? If you were worried about money, don't be. You can come home and live with wour father and me for a while. I'd rather you lived nearer home anyway. Your old boss at the library, Mr.Green, say you could have your old job back if you want it. You could have been Head Librarian by now if you hadn't left ! Anyway, I'll let you know if I hear about any other suitable jobs. Take care and let me know if you make any decisions.

Love, Mum

+Xét a(b+2001) =ab + 2001a

        b(a+2001) = ab + 2001b

Ta xét 3 trường hợp sau:

+ Nếu a>b => 2001a > 2001b

                  => a(b+2001) > b(a+2001)

                  => a/b > a+2001/b+2001

+Nếu a<b => 2001a < 2001b

                  => a(b+2001) < b(a+2001)

                  => a/b < a+2001/b+2001
