Here is some math!

$$\sqrt{3}$$

[silverwind]

When $a \ne 0$, there are two solutions to $(ax^2 + bx + c = 0)$ and they are
$$ x = {-b \pm \sqrt{b^2-4ac} \over 2a} $$

[zeripath]

$$Does it need $\sqrt{3}$ ?$$ $$ x = {-b \pm \sqrt{b^2-4ac} \over 2a} $$ $$\[ x = {-b \pm \sqrt{b^2-4ac} \over 2a} \]$$

[zeripath]

yup looks like fenced blocks don't work

$$\left( \sum_{k=1}^n a_k b_k \right)^2 \leq \left( \sum_{k=1}^n a_k^2 \right) \left( \sum_{k=1}^n b_k^2 \right)$$

This sentence uses $ delimiters to show math inline: $\sqrt{3x-1}+(1+x)^2$

$$\left( \sum_{k=1}^n a_k b_k \right)^2 \leq \left( \sum_{k=1}^n a_k^2 \right) \left( \sum_{k=1}^n b_k^2 \right)$$
