Can someone point me in the right direction to simplify this equation.

1/x+1 - 1/2x+1 = 1/6

Yes I have substituted into the quadratic formula but I only get a positive answer and my workbook suggests
that b2-4ac is negative. I just cant see it

Using the quadratic formula why does

y² + y + 1 = 0

equal a negative answer ??

Thank you

As ever that explains things beautifully.

#7 Re: Help Me ! » Simultaneous Equations » 2011-09-24 18:34:30

So sorry I go the equations wrong

3p-3=3q

and

7p = 1+4q

thanks

Through using substitution how can I solve

3p-3 = q
and
7p=1+4q

so that p=-1 and q=-2

Many Thanks in advance

Hi,

I was hoping someone could explain why

3/√x + √x = 3/√x + √x.√x/√X

when then simplifies further to

3+x/√x

many thanks

#11 Re: Help Me ! » rearranging fractions » 2011-09-22 20:12:10

Wow
Thanks for all your hard work.
Makes perfect sense

#12 Re: Help Me ! » rearranging fractions » 2011-09-22 02:24:06

Fantastic
thanks for all your help
If you have any time left smile then I would like to hear why you can split the fraction because of addition on top and not the bottom.

thanks again

Hi,

Im doing a Maths course and I am finding the basics very difficult. the last time I did Maths was at O Level over 20 years ago and my poor ancient mind seems to have forgotten most of it.

Anyway can anyone help with the following.

Why and how does p+q/pq become 1/q+1/p

How is it possible to simplify (x-√3)(x+√3) to x² - 3

Thanks

How is the following possible.
I realise I may be being very thick about this but I cant see it

4/√2 = 2x2/√2 = 2x√2 x √2/√2 = 2√2

What am I missing
