my goodness, young peoples education these days!

2x20 = 40!

simple maths. Any other maths homework problems?

[MJ_1993]

2/x+1 + 3/x-1 = 5/x(x)-1

the x(x) is meant to be x squared.

I know the answer do you?

Keiran if your that keen to do my maths h.w:

4x-3/2 = 9x-6/8 + 2 3/4

[MJ_1993]

serious?

I know thats not the right answer for the first one!

[kieran]

well, given the complete lack of bracketing in the equation I have had to guess but is the answer : 4/5, using the fact that (x+1)(x-1) = (x^2 -1)

[Tony]

Mo - I think you need to put some brackets in to clarify the equation. I suspect you mean:

2/(x+1) + 3/(x-1) = 5/(x.x -1) where x.x is x^2 (i.e. x-squared).

If so the answer is x = 4/5 (i.e. 0..

You need to multiply all terms in the equation by (x+1)(x-1), cancel the common terms on each numerator and denominator and it simplifies nicely to:

2(x-1) + 3(x+1) = 5 (note that (x+1)(x-1) = (x.x -1) - the difference of two sqaures)).

Gather up the terms to give:

5x + 1 = 5 so x = 4/5.

If you have any more difficult mathematical questions - I'm sure Marek will be able to answer them.

[Tony]

OK - so using brackets confuses the Message Board as it confuses them with smileys.

Notice though that wording in my previous post inadvertently got turned in to the cool smiley. That can't be a coincidence. It must say something about me.

Anyway - we are wondering off topic and everyone is showing off how clever they are.

So who is going to win on Saturday? Is anyone running a book? I know who I favour. Maybe we could have a prize for correctly guessing the winner in each race???? Sealed submissions to Toks before the race.

[kieran]

ha, glad to have confirmation Tony, seems we posted answers exactly the same time so an nice proof of independence (assuming we only communicated via this forum I suspose)


There you go, Mo , see the wealth of talent you can exploit for your h.w., I'm sure others here will be expert in other areas. Sylv - help with French, Marek with Polish etc, we have some artists as well I believe? What subjects you studying ?

[MJ_1993]

yeah the answer is 4/5.

Tony, the question was written like that.

[MJ_1993]

I do all the boring subjects

Economics, History, Geo, French

I might need help with science bcos I hav rubbish teachers.

But that happened last year and I straight A*s in my GCSEs modules.

[kieran]

what's that they say about falling standards?

[MJ_1993]

HA funny

I dont revise and still come 2nd in my year

And have an IQ of 13 less than Einstein
