Embed MathJax code in Zoho Sites?

Is it possible to embed MathJax code into Zoho Sites.

I tried the following and got error: * That's not of the right format. Please verify code.

<!DOCTYPE html>

<head>

<title>MathJax TeX Test Page</title>

<script type="text/x-mathjax-config">

MathJax.Hub.Config({tex2jax: {inlineMath: [['$','$'], ['\$','\$']]}});

</script>

<script type="text/javascript"

When $a \ne 0$, there are two solutions to $ax^2 + bx + c = 0$ and they are

$$x = {-b \pm \sqrt{b^2-4ac} \over 2a}.$$
