### Configuration
To enable MathJax support, just set `plugins.mathjax = true` in your theme `_config.yml` file.

##### Input
```
When $a \ne 0$, there are two solutions to \\(ax^2 + bx + c = 0\\) and they are
$$x = {-b \pm \sqrt{b^2-4ac} \over 2a}.$$
```
##### Result
When $a \ne 0$, there are two solutions to \\(ax^2 + bx + c = 0\\) and they are
$$x = {-b \pm \sqrt{b^2-4ac} \over 2a}.$$
### MathML input
> Attention: please be noted that newline characters will be transformed to ` ` tag by Markdown interpreter and this will interfere with MathML notation. Please write all MathML inline.
