Kua tāruatia ki te papatopenga
y=2^{3}-12\times 2+8
Whakaarohia te whārite tuatahi. Me kōkuhu ngā uara tāupe mōhiotia ki te whārite.
y=8-12\times 2+8
Tātaihia te 2 mā te pū o 3, kia riro ko 8.
y=8-24+8
Whakareatia te -12 ki te 2, ka -24.
y=-16+8
Tangohia te 24 i te 8, ka -16.
y=-8
Tāpirihia te -16 ki te 8, ka -8.
y=-8 x=2
Kua oti te pūnaha te whakatau.
