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

    On the toolbar you see the button \boxed{\Sigma} that will give you [TEX] [/TEX] tags.

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

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

    \frac{3}{4}( \frac{4a^2}{a}+ \frac{ab}{3}- \frac{4ab}{3}-b^2

    I assume you mean \displaystyle \begin{align*} \frac{4a^2}{9} \end{align*}. Otherwise you are correct. Now collect your like terms.

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

    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 \frac{3}{4}.

    There is a Latex tutorial at Physicsforums FAQ

    I'm really wasting your time
    [TEX]\frac{3}{4} [/TEX] gives \frac{3}{4}

    Look at the tool-bar the icon \boxed{\Sigma} gives [TEX] [/TEX] the wrap.
