For installing latexrender wordpress plugin you can find guidelines here
One more thing to remember while setting $latexrender_path_http in latex.php give full http path to latexrender folder like $latexrender_path_http = "http://your blog addr/latexrender";
Now you are set to go. To include [tex]\LaTeX[/tex] in your posting, use the following:

[tex] (a+b)^3 = (a+b)^2(a+b) [/tex]

produces :

[tex](a+b)^3 = (a+b)^2(a+b)[/tex]

But after setting up latexrender plugin, the png image was still not generated. Error that I got was:

I can’t find the format file ‘latex.fmt’!

But when I tried similar command (latex sample.tex) from shell prompt, It was working fine.
So I thought that problem is in calling latex from php file using exec. So when I copied the latex.fmt file to directory containing .tex file it started working fine. May be some problem in setting environment variable.
You can look for latex.fmt file using :

find -name latex.fmt

For latexrender you can copy latex.fmt file to latexrender/tmp/ folder inside your wordpress installation.
I’m still working on how to set environment variable in php so that I don’t have to copy latex.fmt again and again.
But for now I gave got working latex on my blog . Now I can write math equations in my blog posts.
You can try latex formulas in comment too.

And if you want to publish LaTeX equation in WordPress blog without installing any software, try jsTeXrender: http://yourequations.com/. Thanks Doug for the tip.
