=== Algebraintro till boken på sid 3 ===<br />
<br />
[http://sv.wikipedia.org/wiki/Girolamo_Cardano Gerolamo Cardano] funderade över lösingen till följande ekvation <br />
<br />
'''''Kan vi dela talet 8 i två delar så att deras produkt blir 25?'''''<br />
<br />
: <math>x(8-x) = 25</math><br />
<br />
Ekvationen har följande rötter:<br />
<br />
: <math> x = 4 + \sqrt{-9}</math><br />
: <math> x = 4 - \sqrt{-9}</math><br />
<br />
Ekvationen kan skrivas om på detta sätt:<br />
<br />
: <math>8x - x^2 = 25</math><br />
<br />
: <math>x^2 - 8x + 25 = 0</math><br />
<br />
Men vad är roten ur -9? Det är ett imaginärt tal, som skrivs 3''i''. Kolla gärna Wolfram Alpha för en [http://www.wolframalpha.com/input/?i=x%288-x%29%20%3D%2025&t=ff3tb01 lösning] till ekvationen ovan<br />
