title: How to do the Bisection method in Python
body: <p>I want to make a Python program that will run a bisection method to determine the root of: </p>
  
  <pre><code>f(x) = -26 + 85x - 91x2 +44x3 -8x4 + x5
  </code></pre>
  
  <p>The Bisection method is a numerical method for estimating the roots of a polynomial f(x).</p>
  
  <p>Are there any available pseudocode, algorithms or libraries I could use to tell me the answer?</p>
