How to using math jax? : I've been read the docs and I still don't get how to apply it from TeX 

so basically i wanted to convert this string 

   ` <p><span class='math-tex'>\\( x&gt;0,y&gt;0 \\)</span></p>`

`<p><span class='math-tex'>( (\\frac{2}{7},\\frac{2}{18}) )</span></p>`

they are tex version right ? using `\\( \\)`

from my API and I still have no idea how to convert it

    <script>
       MathJax = {
        tex: {
        inlineMath: [['$', '$'], ['\\(', '\\)']],
        }
         };
      </script>
    
    <script type='text/javascript' async
        src='https://cdnjs.cloudflare.com/ajax/libs/mathjax/2.7.5/MathJax.js?config=TeX-MML-AM_CHTML'>
        
    </script>
    <p>
     <span class='math-tex'>( (\\frac{2}{7},\\frac{2}{18}) )</span> 
    </p>
