Kua tāruatia ki te papatopenga
y=3^{3}-12\times 3+8
Whakaarohia te whārite tuatahi. Me kōkuhu ngā uara tāupe mōhiotia ki te whārite.
y=27-12\times 3+8
Tātaihia te 3 mā te pū o 3, kia riro ko 27.
y=27-36+8
Whakareatia te -12 ki te 3, ka -36.
y=-9+8
Tangohia te 36 i te 27, ka -9.
y=-1
Tāpirihia te -9 ki te 8, ka -1.
y=-1 x=3
Kua oti te pūnaha te whakatau.
