Kua tāruatia ki te papatopenga
2y^{3}=2y^{3}
Tē taea kia ōrite te tāupe y ki tētahi o ngā uara -8,0 nā te kore tautuhi i te whakawehenga mā te kore. Me whakarea ngā taha e rua o te whārite ki te 2\left(y+8\right)y^{3}, arā, te tauraro pātahi he tino iti rawa te kitea o 2y^{4}+16y^{3},y+8.
y\in \mathrm{C}
He pono tēnei mō tētahi y ahakoa.
y\in \mathrm{C}\setminus -8,0
Tē taea kia ōrite te tāupe y ki tētahi o ngā uara 0,-8.
