Oh I got it now, thx! I'll try to write the whole thing now

If you type [TEX]\left(\frac{3a}{4}-b\right) [/TEX] you will get

On the toolbar you see the button that will give you [TEX] [/TEX] tags.

You need a backslash, not forward slash. Try \frac{3}{4}

How do I write "a*a" ?

You could try "a \cdot a" or "a \times a" or even "a^2"...

( + - -b^2

I forgot to wrap up with a ")", and the end was'nt right. But I'm improving, thx. My pc dies now, I have no charger, I hope to get more help from you later. Thank you so much for your patience!

I assume you mean . Otherwise you are correct. Now collect your like terms.

Also, it's best to write your entire mathematical expression in the tex tags.

Yea thats what I meant, made a mistake as I was in a hurry.

So now collect your like terms to simplify...

First, you have to start and end with [ t e x ] and [ \ t e x ] tags- without the spaces, which I put on so it would not be interpreted as "Latex" tags and so you could see them. Also you need to put the numerator and denominator in "braces", { }. [ t e x ]\frac{3}{4}[/ t e x] without the spaces gives .

Ok I think I've got it, thx!

I'm really wasting your time

[TEX]\frac{3}{4} [/TEX] gives

Look at the tool-bar the icon gives [TEX] [/TEX] the wrap.
