Whakaoti i te 0=a(20-10)^2+6

$$0 = a ( 20 - 10 ) ^ { 2 } + 6$$

Whakaoti mō a

$$a=-\frac{3}{50}=-0.06$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Tangohia te 10 i te 20, ka 10.

$$0=a\times 10^{2}+6$$

Tātaihia te 10 mā te pū o 2, kia riro ko 100.

$$0=a\times 100+6$$

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

$$a\times 100+6=0$$

Tangohia te 6 mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.

$$a\times 100=-6$$

Whakawehea ngā taha e rua ki te 100.

$$a=\frac{-6}{100}$$

Whakahekea te hautanga \frac{-6}{100} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.

$$a=-\frac{3}{50}$$
