Помогите пожалуйста найти мод, который бы изменял формулу (в одну строку), например

x=(-b±√(b^2-4ac))/2a

Installation (Again, partially stolen from Dave’s documentation.) Create a folder somewhere web-accessible to hold all of your generated images. You need to create two sub-directories called tmp and img inside this folder, and make them both world-writable. Extract the archived ZIP file somewhere. Carefully read through the configuration in class.latex-vb.php (at the beginning of the file) and fill in all required sections. Make sure your paths are correct and agree with step 1. Upload the class.latex.php and ipbLatex.php files to the /admin/sources/classes/bbcode/custom directory of your IP.Board installation. Open templates.txt. To enable the LaTeX popup feature, which allows your users to see the LaTeX code that generated a formula by clicking it, you need to edit your default templates. You’ll have to do this for every style you have installed. Simply follow the directions in templates.txt. Head to your administration panel, to Look & Feel -> BBCode Management. Scroll to the bottom, at Import New BBCodes. Browse and select the bbcode.xml file that came with the plugin. Install it. That’s it! By default, the plugin uses the [latex] and [math] tags as synonyms, with [imath] and [ce] representing inline math and chemical equations, respectively. You can add additional synonyms as aliases in IPB’s BBCode editor, but note that [imath] and [ce] are hardcoded, and they won’t work if you change the aliases for those. With ipbLatex installed, you should be able to use LaTeX anywhere that BBCode can be used — personal messages, in the forums, and wherever. All images are stored in the img directory you create for all time, so you may wish to periodically cull that directory. (If a user previews their post, then changes an equation before posting it, the old equation will remain for all time.) At SFN we commonly see an img directory of over 20,000 images, so be careful opening it in your FTP client or you may cause it to hang. If images are deleted, never fear, ipbLatex will merely recreate once the posts are viewed. If you need extra LaTeX packages for additional features, you can always add more to the ‘extrapackages’ list in the configuration. By default, the AMS math packages are loaded, as well as color and slashed.

 

Подскажите пожалуйста как его установить.

1. Создал папки с правами
