Hello. I registered today. Maybe you can help me. How do I use LaTex in the forum for to write equations?

$a^2+b^2=c^2$

Please have a look at https://www.physicsforums.com/help/latexhelp/

Webservers do not use TeX, they use various versions of MathJax because the technical demands are different on a client-server architecture versus a compiler architecture on a single platform system. The link above tells you about the differences here.

##a^2+b^2=c^2## or [itex]a^2+b^2=c^2[/itex] results in $a^2+b^2=c^2$
$$a^2+b^2=c^2$$ or [tex]a^2+b^2=c^2[/tex] results in $$a^2+b^2=c^2$$

Thank you very much fresh_42 . Cordial greetings.

$$ax^2 + bx + c = 0$$

All of your threads require way more explanations, references, and reports about what you have done, searched, or read so far. I'm afraid these fragments of yours will directly lead to problems here. If it is a language issue, then please use https://translate.google.com/

I am using google translator. Maybe I don't know how to take advantage of all its functions.
I honestly assumed that in the questions I had expressed what I was interested in finding out. Now I notice that it hasn't turned out well.Thanks for your support.
