Kua tāruatia ki te papatopenga
2x+16=0
Tē taea kia ōrite te tāupe x ki tētahi o ngā uara -2,2 nā te kore tautuhi i te whakawehenga mā te kore. Whakareatia ngā taha e rua o te whārite ki te \left(x-2\right)\left(x+2\right).
2x=-16
Tangohia te 16 mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
x=\frac{-16}{2}
Whakawehea ngā taha e rua ki te 2.
x=-8
Whakawehea te -16 ki te 2, kia riro ko -8.
