Kua tāruatia ki te papatopenga
0\times 5x^{3}-6x+8=0
Tē taea kia ōrite te tāupe x ki tētahi o ngā uara 0,1 nā te kore tautuhi i te whakawehenga mā te kore. Whakareatia ngā taha e rua o te whārite ki te \left(x-1\right)x^{2}.
0x^{3}-6x+8=0
Whakareatia te 0 ki te 5, ka 0.
0-6x+8=0
Ko te tau i whakarea ki te kore ka hua ko te kore.
8-6x=0
Tāpirihia te 0 ki te 8, ka 8.
-6x=-8
Tangohia te 8 mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
x=\frac{-8}{-6}
Whakawehea ngā taha e rua ki te -6.
x=\frac{4}{3}
Whakahekea te hautanga \frac{-8}{-6} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te -2.
