Whakaoti i te 19.6=a(2^2)+b(2)

$$19.6 = a( { 2 }^{ 2 } )+b(2)$$

Whakaoti mō a

$$a=-\frac{b}{2}+4.9$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Tātaihia te 2 mā te pū o 2, kia riro ko 4.

$$19.6=a\times 4+b\times 2$$

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

$$a\times 4+b\times 2=19.6$$

Tangohia te b\times 2 mai i ngā taha e rua.

$$a\times 4=19.6-b\times 2$$

Whakareatia te -1 ki te 2, ka -2.

$$a\times 4=19.6-2b$$

He hanga arowhānui tō te whārite.

$$4a=19.6-2b$$

Whakawehea ngā taha e rua ki te 4.

$$\frac{4a}{4}=\frac{19.6-2b}{4}$$

Mā te whakawehe ki te 4 ka wetekia te whakareanga ki te 4.

$$a=\frac{19.6-2b}{4}$$

Whakawehe 19.6-2b ki te 4.

$$a=-\frac{b}{2}+\frac{49}{10}$$

Whakaoti mō b

$$b=9.8-2a$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Tātaihia te 2 mā te pū o 2, kia riro ko 4.

$$19.6=a\times 4+b\times 2$$

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

$$a\times 4+b\times 2=19.6$$

Tangohia te a\times 4 mai i ngā taha e rua.

$$b\times 2=19.6-a\times 4$$

Whakareatia te -1 ki te 4, ka -4.

$$b\times 2=19.6-4a$$

He hanga arowhānui tō te whārite.

$$2b=19.6-4a$$

Whakawehea ngā taha e rua ki te 2.

$$\frac{2b}{2}=\frac{19.6-4a}{2}$$

Mā te whakawehe ki te 2 ka wetekia te whakareanga ki te 2.

$$b=\frac{19.6-4a}{2}$$

Whakawehe 19.6-4a ki te 2.

$$b=\frac{49}{5}-2a$$
