&lt;p&gt;&lt;b&gt;Ny sida&lt;/b&gt;&lt;/p&gt;&lt;div&gt;Exempel:&lt;br /&gt;
&lt;br /&gt;
Korthandsberäkna (a+b)² som polynom&lt;br /&gt;
&lt;br /&gt;
{| class=&amp;quot;wikitable&amp;quot;&lt;br /&gt;
|-&lt;br /&gt;
| x || a || b&lt;br /&gt;

&lt;br /&gt;
(a+b)² = a²+ab+ab+b² = a²+2ab+b²&lt;br /&gt;

(2x-3y)² = 4x²-6xy-6xy+9y² = 4x²-12xy+9y²&lt;br /&gt;
