<h2>Test quadratic polynomials</h2>

Mathematicians discovered, that some polynomials of the general form<br />
<img src="quadratic" /><br /> produce more prime numbers for a range of input values than others.

<a href="http://en.wikipedia.org/wiki/Leonhard_Euler" target="_blank">Leonhard Euler</a>
found the polynomial<br />
<img src="eulerpolynom" /><br />, that produces prime numbers for all input values <i>x</i> from 0 to 39.<br />

With this dialog, you can look for polynomials that produce many prime n
