&lt;br /&gt;
&amp;lt;math&amp;gt; x^2 - 6\,x + 8 = 0 &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Ekvationen ovan ger Vietas formler (se Teori 3 Samband mellan koefficienter och nollställen):&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; \begin{align} x_1   +   x_2 &amp;amp; = -(-6) = 6   \\&lt;br /&gt;
                      x_1 \cdot x_2 &amp;amp; = 8&lt;br /&gt;
        \end{align}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Man hittar lösningarna &amp;lt;math&amp;gt; x_1 = 2\,&amp;lt;/math&amp;gt; och &amp;lt;math&amp;gt; x_2 = 4\,&amp;lt;/math&amp;gt; eftersom&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; \begin{align}    2   +   4  &amp;amp; = 6   \\&lt;br /&gt;
                        2\cdot  4  &amp;amp; = 8&lt;br /&gt;
