## MathJax example

**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} \\]
```

**Output**:

When \( a \ne 0 \), there are two solutions to

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

and they are:

\[ x = {-b \pm \sqrt{b^2-4ac} \over 2a} \]
