if you have an equation like 6x+12= 8x-24 what would that equal

It will only be equal if

6x+12= 8x-24

12= 2x-24

36= 2x

x=18

It will not be equal for any other value of x  :)

Only Mr Massow can answer your question

BUT

can't you just magnify your screen ?

YES and these are all square numbers too :))

Good thinking guest :)

Do you understand it up to here  ?

\((x-2)(x^2+bx+c)=x^3-4x^2-11x+30\)

The bit in the box is just equating coefficients.

On the LHS the x^2 terms are      \(bx^2\;\; and \;\;-2x^2\)  

and on the right the x^2 term is      \( -4x^2\)

so

\(bx^2\;\;\ +\;\; -2x^2\;=\;-4x^2\\ (b-2)x^2=-4x^2\\ b-2=-4\\ b=-2\\ \)

Is that all you need help with ?

Thanks Max,

I will add this to our LaTex thread that is kept with the sticky topics.

This thread is in a bit of a mess I am afraid but I still find it useful occasionally.

If you want to voluteer to do a new cleaned up version that would be really good.

(You would just need to include the address of the original one so we don't lose it)

If you don't want to or do not have time that is fine.  :)

Also,

If you are usually able to edit your posts you are really lucky.  Most of us, including me, are never able to do that any more.  We used to be able to but it has not worked for a long time now.  That is one of the reasons that things are no longer well organised.  Many threads really need the editing ability to keep them tidy. :(
