&lt;p&gt;&lt;b&gt;Ny sida&lt;/b&gt;&lt;/p&gt;&lt;div&gt;Mittpunkten till olikhetens lösningsintervall &amp;lt;math&amp;gt; \,-4 &amp;lt; x &amp;lt; 6 &amp;lt;/math&amp;gt;:&lt;br /&gt;
&lt;br /&gt;
::&amp;lt;math&amp;gt; {-4 + 6 \over 2} = {2 \over 2} = 1 &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Intervallets halva längd:&lt;br /&gt;
&lt;br /&gt;
::&amp;lt;math&amp;gt; \left| {-4 - 6 \over 2} \, \right| = \left| {-10 \over 2} \, \right| = | -\,5 \, | = 5 &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Därmed kan intervallet skrivas om till olikeheten:&lt;br /&gt;
&lt;br /&gt;
::&amp;lt;math&amp;gt; | \, x \,- {\rm mittpunkt} \, | &amp;lt; \, {\rm halva\;längd} {\color{White} x} = {\color{White} x} | \, x - 1 \, | &amp;lt; 5  &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Intervallet &amp;lt;math&amp;gt; -4 &amp;lt; x &amp;lt; 6 \, &amp;lt;/math&amp;gt; kan skrivas om till olikheten &amp;lt;math&amp;gt; | \, x -1 \, | \, &amp;lt; \, 5 &amp;lt;/math&amp;gt; .&lt;/div&gt;</summary>
