title: What is an algorithm for solving quadratic with linear equation simultaneously?
body: <p>Need an algorithm to solve equation like these:</p>
  
  <pre><code>8*p^2+8*q^2+8*p-16=0
  p^2+q^2+12*p+20=0
  </code></pre>
  
  <p>If anyone can point me to the name of algorithm also it'll be enough. I could have followed any matrix related algorithm but the quadratic inside these linear are causing a problem.</p>
