This examples shows how to load a specify list of components rather
than one of the combined components. In this case, we load the base
TeX component, the newcommand extension, the action extension, and the
CHTML output component. The CHTML output is configured to use the
mathjax-newcm font, since the individual output
components don't automatically load a font.
When $a \ne 0$, there are two solutions to \(ax^2 + bx + c = 0\) and they are $$x = {-b \pm \sqrt{\texttip{b^2-4ac}{descriminant}} \over 2a}.$$
This example shows how to mix-and-match the components that are
loaded (if there isn’t a combined component that includes what you
need). This is done by setting the load array in the
loader section of you MathJax configuration, as shown
below.
Here, we specify the tex-base input jax (which is TeX
with no extra packages included), and explicitly load the
newcommand and action extensions. We also
load the chtml output jax, and configure it to use the
mathjax-newcm font, since the stand-alone output
components don't include a font themselves.
The TeX configuration registers the loaded packages with the TeX input jax (it is possible to load extensions without initially enabling them), and adds dollar signs as in-line math delimiters.
