Kua tāruatia ki te papatopenga
y=\left(-161\right)^{2}+300\left(-161\right)+19561
Whakaarohia te whārite tuatahi. Me kōkuhu ngā uara tāupe mōhiotia ki te whārite.
y=25921+300\left(-161\right)+19561
Tātaihia te -161 mā te pū o 2, kia riro ko 25921.
y=25921-48300+19561
Whakareatia te 300 ki te -161, ka -48300.
y=-22379+19561
Tangohia te 48300 i te 25921, ka -22379.
y=-2818
Tāpirihia te -22379 ki te 19561, ka -2818.
y=-2818 x=-161
Kua oti te pūnaha te whakatau.
