<p>there is a thread called June Math IIC… why did you make a whole new thread for one specific question on that test?</p>

<p>it was something of the sort of…Ax^5 + Bx^4 + Cx^3 + Dx^2 + Ex + F (maybe) and the question was “What is the least number of positive real roots?”</p>

<p>I believe the answer was Zero (a) by DeCarte’s Theorem.</p>

<ol>
<li><p>I used descartes theorem and found the answer to be 5 possible negative roots according to that.</p></li>
<li><p>Descartes theorem states that there would be 0 positive roots and 1,3, or 5 negative roots. Therefore the answer is 1. this is the only question I think I got wrong. I put 5 as my final answer.</p></li>
