# Thread: My english sets an early limit to my describtion, sorry

1. ## My english sets an early limit to my describtion, sorry

3/4(1/3a-b)(4/3a+b)

My attempts failed, walk me through please?

2. ## Re: My english sets an early limit to my describtion, sorry

Some LaTeX or brackets used correctly would be nice... Is it \displaystyle \begin{align*} \frac{3}{4}\left(\frac{1}{3}a - b\right)\left(\frac{4}{3}a + b\right) \end{align*} as it's written, or something else?

Is your problem $\frac{3}{4}\left( {\frac{1}{{3a - b}}} \right)\left( {\frac{4}{{3a + b}}} \right)~?$

Or is it something altogether different?

You need to learn to use grouping symbols.

Sincerely appologize for the confusion, I have no idea how to write numbers correctly online like this, I'll work on that. But yes Prove It, you understood it correctly.

Do you know how to expand brackets?

Yes I do

9. ## Re: My english sets an early limit to my describtion, sorry

Start by expanding the brackets...

Again, still dont know how to write it correctly. How do I write for example "1/3" the way you did? :S

11. ## Re: My english sets an early limit to my describtion, sorry

In tex tags, you write a fraction as \frac{}{} with your numerator inside the first set of curly brackets and your denominator inside the second set of curly brackets.

{3}{4}({4a}{a}+{ab}{3}-{4ab}{3}-b)

13. ## Re: My english sets an early limit to my describtion, sorry

You know what, I give up, really sorry I bothered you. I'll find help elsewhere. Thank you anyways!

14. ## Re: My english sets an early limit to my describtion, sorry

Don't give up. You need to wrap the coding inside tex tags. They look like [ tex ] and [ /tex ] (just without the spacing).

Trying to write "3/4", this is what I get: $/frac{3}{4}$
