Whakaoti i te 13=15(0)^2/2+9(0)+c

$$13 = 15 \frac { ( 0 ) ^ { 2 } } { 2 } + 9 ( 0 ) + c$$

Whakaoti mō c

$$c=13$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Whakareatia ngā taha e rua o te whārite ki te 2.

$$26=15\times 0^{2}+18\times 0+2c$$

Tātaihia te 0 mā te pū o 2, kia riro ko 0.

$$26=15\times 0+18\times 0+2c$$

Whakareatia te 15 ki te 0, ka 0.

$$26=0+18\times 0+2c$$

Whakareatia te 18 ki te 0, ka 0.

$$26=0+0+2c$$

Tāpirihia te 0 ki te 0, ka 0.

$$26=2c$$

Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.

$$2c=26$$

Whakawehea ngā taha e rua ki te 2.

$$c=\frac{26}{2}$$

Whakawehea te 26 ki te 2, kia riro ko 13.

$$c=13$$
