I'd like to write a questions but I don't understand how to write formulas, why if I write [ tex ] \phi[ / tex ] the preview doesn't show me any formula? thank you
Is it ok if I attach a photo of the formulas instead of writing them?

It does work if you omit all five of the spaces within the brackets.

Or double hashes for inline formulas. E.g.

With ##a = 1## we have:
$$x = \frac{-b \pm \sqrt{b^2 -4c}} {2}$$
