nak try jwab soklan mathematics ne tak..
Hy everyone.. saje je ne post Qs abt mathematics... tengah bosan ne.. soklan senang je niThe Qs are:
1. Express as a partial fractions : (a) 4/x^2-4
(b) 4/ (x-3)(x+1)
2. By means of substituition u = x^-1/2, or otherwise solve the equation x^-1/2 +2x^-1 = 21
:D:victory: Good Luck...

Salam,1.(a) I assume your question was 4/(x^2-4), with the parentheses. The answer is 1/(x-2) - 1/(x+2).
1.(b) 1/(x-3) - 1/(x+1)
2. After substitution, we get
u+2u^2=21
u = 3 OR u = -7/2
Hence
x = 1/9 OR x = 4/49
Then again I have always been annoyingly CARELESS and RECKLESS :L . So please check again.

Anyway, daisyisara, please stop posting such question on this board, because these forum users are not ready to be challenged nor give any thought about any serious talk.So just lay back and treat this forum as a theatre. Most people here prefer leisure talk. A thoughtful thread can quickly turn absurd.
As a newbie too, I just had to learn about it the hard way.

jawapan dia btul... :D :D :D haaa.... try ni plak.... 1+1 = ? :lol:Reply #6 aku_EnSeM's post
binary ker decimal?:$Reply #7 isskandar's post
binary... :lol:aku bru teringat, sorg lecturer ni try buat lawak kt klas...
kt slide die tulis "Ade 10 jenis org kt dunia ni... 1 jenis paham binary, 1 lg x paham binary"...
mule2 sunyi sepi je je hall tu... xlme pastu bru org gelak... :lol: Originally posted by aku_EnSeM at 4-2-2009 01:56 PM http://mforum4.cari.com.my/images/common/back.gif
