Tibixda (b2-4ac) ee isle'eg saabley ee leh sansaanka ax2+bx+c=0. Haddii xididdada isle'egtu ay isle'egyihiin, takooraha waa eber. Tusaale ahaan, isle'egta x2-4x-6=0, b2-4ac=25 xididdaduna waa 2 iyo -3. Haddii takooruhu yahay tabane, xididdada isle'egtu waa tirooyin murakab ah. Tusaale ahaan, isle'egta x2+x+1=0 waxa ay leedahay xididdada [-1/2-(V3/2)]i iyo [-1+(V3/2)]i.
