When I copy the contents using "copy as internal format" I get the following set of LaTex text. I think Scientific Workplace uses "$" signs by default just like this site, I presume, uses "\[...[/text]".
\[038<p type="texpara" tag="Body Text" >Hi
038<p type="texpara" tag="Body Text" >Would you please tell me if the solution is correct?$\bigskip $
When I only copy the equation I get this:
\[$x=(2+\root{2}\of{-121})^{1/3}+(2+\root{2}\of{-121})^{1/3}=\allowbreak x=2\root{3}\of{\left( 2+11i\right) }$\]
Can you post the LaTeX? It's hard to say what's wrong without the code. It could anything, from a problem with the code, to a problem with the compiler.
Also, some extra stuff: You may like TexMaker, it looks a lot more modern. And, to check problems like that, Wolfram Alpha comes in handy. It can simplify expressions and much more.
Unless text is enclosed in $'s or /[ /], it is assumed to be plain text. If you're wondering about including plain text in [ tex ] [/ tex ] tags, then you can use the \mbox{} command. Unfortunately, it doesn't work on this site, but I've known it to work on others, like Physics Forum, for example.
If you have used Scientific Workplace or Scientific Notebook you would know that after creating a Latex text there one has to copy the text from the Scientific editor using "copy as internal format" from "Edit" menu to paste it on forums like this one.
This is text I had there: **broken link removed**
The pasted text is below:
038<p type="texpara" tag="Body Text" >This is a quadratic equation: $ax^{2}+bx+c=0$
038<p type="texpara" tag="Body Text" >To solve such an equation is taught in schools.
I don't know the purpose of these prefixes "038<p type="texpara" tag="Body Text" >". Perhaps, it's part of Latex formatting. But the main issue is it doesn't compile into Latex image.
