How i can render both markdown and Latex ?

[summonerriftofficial]

I have a markdown and latex togther, how I can render them together?

"Find the value of $k$, if $x + 6$ is a factor of $- k + x^{3} + 16 x^{2} + 76 x$ <br/> [GitHub Link](https://github.com/iwasrobbed/Down)"

            let downView = try DownView(frame: view.bounds, markdownString: readMeContents, didLoadSuccessfully: {
                print("Markdown was rendered.")
            })

Please ask these sorts of questions on StackOverflow.com first and at the very least detail out what you've tried and what hasn't worked instead of deferring all of the work onto us.
