Whakaoti mō r
r=1
Tohaina
Kua tāruatia ki te papatopenga
0=r\left(-1\right)+1
Tē taea kia ōrite te tāupe r ki 0 nā te kore tautuhi i te whakawehenga mā te kore. Whakareatia ngā taha e rua o te whārite ki te r.
r\left(-1\right)+1=0
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
r\left(-1\right)=-1
Tangohia te 1 mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
r=1
Me whakarea ngā taha e rua ki te -1.
