$\displaystyle \frac{x+3}{x}-\frac{2}{x-2}=0$

Will somebody please explain how I can get a minus sign between the first fraction and the second so that I can put the minus sign between the division lines of the first and second fractions please?

Thanks

David

Thank you Quacky for that useful information

Now for the next part.

$\displaystyle \(x-2)(x+3)\div(x)(x-2)}$$\displaystyle -\(2x)\div(x^2 -2)=0$

It does not seem to be formatting as previously, I need more help and experience as I must be doing something incorrect?

I will have to come back to this later?
