Whakaoti i te 34.8=x*4.4+0.5*-1.4*4.4^2

$$34.8=x \times 4.4+0.5 \times -1.4 \times { 4.4 }^{ 2 }$$

Whakaoti mō x

$$x = \frac{3022}{275} = 10\frac{272}{275} \approx 10.989090909$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Whakareatia te 0.5 ki te -1.4, ka -0.7.

$$34.8=x\times 4.4-0.7\times 4.4^{2}$$

Tātaihia te 4.4 mā te pū o 2, kia riro ko 19.36.

$$34.8=x\times 4.4-0.7\times 19.36$$

Whakareatia te -0.7 ki te 19.36, ka -13.552.

$$34.8=x\times 4.4-13.552$$

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

$$x\times 4.4-13.552=34.8$$

Me tāpiri te 13.552 ki ngā taha e rua.

$$x\times 4.4=34.8+13.552$$

Tāpirihia te 34.8 ki te 13.552, ka 48.352.

$$x\times 4.4=48.352$$

Whakawehea ngā taha e rua ki te 4.4.

$$x=\frac{48.352}{4.4}$$

Whakarohaina te \frac{48.352}{4.4} mā te whakarea i te taurunga me te tauraro ki te 1000.

$$x=\frac{48352}{4400}$$

Whakahekea te hautanga \frac{48352}{4400} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 16.

$$x=\frac{3022}{275}$$
