Tiro kakan

Waxaa suurtagal ah tiro kakan in ay matasho qaab lamaanayaasha hoorsan ah ee tirada maangalka ah

Tiro kakan waa tiro loo qoro qaab isku beegnaan ah 1----1 ama $a+bi\,$ halka $a$ iyo $b$. ayaa ka dhaxeysa baraha xarriiq tiro iyo tirooyinka maangalka ah, taasoo inoo fududeyneysa shaqaynta Aljabraha. Tusaale ahaan ma jirto tiro maangal ah oo raalligelineysa isle'egta : $x^{2}+1=0$. Isle'egta iyo wixii la mid ah si aynu u furfurno waxaynnu adeegsaneynaa ururka tirooyinka kakan.

Tirooyinka habdhiskaa ku jiraa waxey ka koobanyihiin, lammaanayaal hoorsan oo maangal ah (a, b). Sidaa daraadeed, way inoo suuragelaysaa inaynu iskubeegnaan 1------1 ka dhaxeysiino tirooyinka kakan iyo dhibcaha sallax ka koobanyahay. Guud ahaan Zi waxey u taagantahay lamaanayaal hoorsan oo tirooyinka maangalka ah K-na waxey u taagantahay ururka tirooyinkaa oo dhan.

Haddii :$z_{1}\in k,z_{2}\in k,$ oo $z_{2}\neq (0,0);$ markaa :${\cdot }{\frac {z_{1}}{z_{2}}}={z_{1}}{z-1_{2}}$

go'aanka halkaas inooga soo baxaya waa in:

$\,\left({c,o \over c,o}\right)=(a,0){(c,0)^{1}}$

= ( a , 0 ) :$=\{{\cdot }{\frac {1}{c}},0\}.$

= [${\cdot }{\frac {a}{c}}-0,a.0+0.{\frac {1}{c}}$]
