Maths help ,,,,agggainnn

[Brian d marge]

Sorry about this , but i keep getting the same answer , pretty sure somethings askew , as when I use this computer thingy it plots whot it should ( probably tired and cant see wood for trees

need to expand

0= ( X+7) ( X+3 ) ( X-2 )

the answer I keep getting is X^3 +8X^2+x -48

got a feeling thats a crap answer

Thanks in advance

I'm no maths genius but I reckon you're right with your suggestion that it's a crap answer.

It's also a crap question.

WTF?

[spookytooth]

just get rid of the x its a letter not a number then its 7 or just go with xxxx and the ansers beer

Everyone loves an Einstein.........

or any stein for that matter.........

[KoroJ]

Might be: x^3 + 8x^2 + x - 42 ??

but it's been a long time since I did any of this stuff.

One afternoon at Cheers, Cliff Clavin was explaining the Buffalo Theory to his buddy Norm.
Here's how it went:

"Well ya see, Norm, it's like this. A herd of buffalo can only move as fast as the slowest buffalo. And when the herd is hunted, it is the slowest and weakest ones at the back that are killed first. This natural selection is good for the herd as a whole, because the general speed and health of the whole group keeps improving by the regular killing of the weakest members. In much the same way, the human brain can only operate as fast as the slowest brain cells. Excessive intake of alcohol, as we know, kills brain cells. But naturally, it attacks the slowest and weakest brain cells first. In this way, regular consumption of beer eliminates the weaker brain cells, making the brain a faster and more efficient machine. That's why you always feel smarter after a few beers."

THis is the expansion

[x^3] +[8x^2] -[5x] -[84]

I put the [] around so u can see the individual terms.

[doc]

x = 42 yep go for it

you haven't given an answer.

[LardEmbargo]

I dunno.

I got

x^3

+ 8x^2

+ x

= 42

so maybe x = 2?

but I probably arsed it up somewhere. It's maffs innit.

Stay inside the square man. Unless your a freek !!!!

[LardEmbargo]

ok so now I've submitted it there's no way that can be right.

-sigh- I'm such a tard.

Back to the vegetable maffs class for me :(

[Jantar]

you haven't given an answer.

He has. But its the wrong answer.

KoroJ got it correct. Remember the task is to expand, not to solve.

LardEmbargo has solved it correctly.

[The Pastor]

you haven't given an answer.

Didnt say I had.


He didnt ask for one either.
