[Maths HELP!] Factorising...

[Issac]

yes, but do you understand?

 

[Agjsdfd]

Yes I do.
If you put it in brackets you have to multiply each number. Than you get:

2√2+2 over 2

2 and 2 cancels down.

2√2+1

is my understanding right?

 

[moozxy]

And the 2√2 goes down to √2. You divide everything on top.

 

[Agjsdfd]

But the question wants me to write it in the form of " a√b+c "

 

[moozxy]

a=1

 

[Issac]

yes exactly... divide ALL terms!

and moozxy is right too: a=1 is valid and you don't write ones when they are multiplied with something

 

[Agjsdfd]

LoL yah.
so its XXXXXX

excellento.

I think its correct.

 

[Endogene]

something magical just happened...
I understood what happened... wow

 

[Agjsdfd]

Thats anozer question:
By the way, I remember something about reciprocal.
So reciprocal of 2 is 1 over 2?

Am I correct?

 

[Issac]

LoL yah.
so its 1+2?2

excellento.

I think its correct.

no.. 1+?2... not 2?2

(2?2 + 2) / 2

2?2 / 2 + 2/2 = ?2 + 1

Indeed you are

 

[Agjsdfd]

But thats "√2 + 1"
not the form of my answer..

anywayz, never mind that question. Its confusing me. I already had 2 question on that chapter in the non-calc. So less chance of getting harder question + the exam is 2pm tmorrow, am goin to college in the morning to revise with my mates.

 

[Issac]

hey it doesn't differ from the form you are looking for.

a + b√c

well a = 1, b = 1... there you go

1 + 1*√2

it doesn't differ!

 

[xcalibur]

1 + 1√2

a= 1
b=1
c=√2

 

[Agjsdfd]

LOL,
yah. I needed to think a bit sharper.. hope my head will be with me in the exam tomorrow. lol.

 

[Issac]

kamui... don't study any more
it has negative effect this late / soon before a test...

relax and let the things you now know sink deep into your knowledge base!

 

[Agjsdfd]

I got Insomnia mate.
Usually trying to find a way to sleep, but today I dont think so...
My brain is totally turned on now, am not feeling tired..

 

[Issac]

aye man... insomnia probably doesn't have anything to do with it... the study thing I mean..
too soon before a test, your brain can't take in the information, and store it correctly, the most probably thing that will happen is: You read more, that destroys some things you actually know, and in the end you know less.... it's basicly that way... for most people! I won't say it will happen to you, but to be on the safe side, i'd calm down a bit and atleast try to get some rest.

 

[wiithepeople]

yeah, i know how you feel, I think I'm an insomniac too.

Bleh, I'm supposed to be doing math now, too...
mathematical induction crap, I hate it cause you have to prove formulas and write like half a page per question.

 

[Agjsdfd]

Hehe awright.

Thanx for the help everyone, special thanks to Issac for the help.

No more questions!

Hehe... This saturday I wrote an exam test in 3-D Computer Graphics... 6 questions... i handed in 12 pages...

4 hours... it was not nice! not at all! (it was the same questions as a previous test but much much harder... AND less points per question

it sucked big time)

@kamui:

No problems man

I'm happy to help... I'm the helpful one here
