Whakaoti i te -4^2-4-1left(-k+2right)=0

$${ -4 }^{ 2 } -4-1 \left( -k+2 \right) = 0$$

Whakaoti mō k

$$k=-10$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Tātaihia te -4 mā te pū o 2, kia riro ko 16.

$$16-4-\left(-k+2\right)=0$$

Tangohia te 4 i te 16, ka 12.

$$12-\left(-k+2\right)=0$$

Hei kimi i te tauaro o -k+2, kimihia te tauaro o ia taurangi.

$$12-\left(-k\right)-2=0$$

Tangohia te 2 i te 12, ka 10.

$$10-\left(-k\right)=0$$

Tangohia te 10 mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.

$$-\left(-k\right)=-10$$

Whakawehea ngā taha e rua ki te -1.

$$-k=\frac{-10}{-1}$$

Ka taea te hautanga \frac{-10}{-1} te whakamāmā ki te 10 mā te tango tahi i te tohu tōraro i te taurunga me te tauraro.

$$-k=10$$

Me whakarea ngā taha e rua ki te -1.

$$k=-10$$
