Kua tāruatia ki te papatopenga
y=\left(-131\right)^{2}+300\left(-131\right)+19561
Whakaarohia te whārite tuatahi. Me kōkuhu ngā uara tāupe mōhiotia ki te whārite.
y=17161+300\left(-131\right)+19561
Tātaihia te -131 mā te pū o 2, kia riro ko 17161.
y=17161-39300+19561
Whakareatia te 300 ki te -131, ka -39300.
y=-22139+19561
Tangohia te 39300 i te 17161, ka -22139.
y=-2578
Tāpirihia te -22139 ki te 19561, ka -2578.
y=-2578 x=-131
Kua oti te pūnaha te whakatau.
