<p>After reading tips 4, 13, 15 22, and 37 several times, I still can’t find a way to understand them, so if anyone can get me videos (preferably on youtube) pertaining to these tips I would be very thankful!</p>
<p>I honestly was thinking the same thing!</p>

<li>AoPS has a good article on Vieta’s formulas:
[Vieta’s</a> Formulas - AoPSWiki](<a href=“http://www.artofproblemsolving.com/Wiki/index.php/Vieta’s_Formulas]Vieta’s”>Art of Problem Solving)</li>
</ol>
<p>I can’t really see tips 13, 15, 22, 37 since I don’t have that book and I’m only going off of the preview on Amazon, but there are some great resources online!</p>
