Ngā Upane Otinga

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

$$\frac{-4\sqrt{16-4\left(-3\right)}}{2}$$

Whakareatia te 4 ki te -3, ka -12.

$$\frac{-4\sqrt{16-\left(-12\right)}}{2}$$

Ko te tauaro o -12 ko 12.

$$\frac{-4\sqrt{16+12}}{2}$$

Tāpirihia te 16 ki te 12, ka 28.

$$\frac{-4\sqrt{28}}{2}$$

Tauwehea te 28=2^{2}\times 7. Tuhia anō te pūtake rua o te hua \sqrt{2^{2}\times 7} hei hua o ngā pūtake rua \sqrt{2^{2}}\sqrt{7}. Tuhia te pūtakerua o te 2^{2}.

$$\frac{-4\times 2\sqrt{7}}{2}$$

Whakareatia te -4 ki te 2, ka -8.

$$\frac{-8\sqrt{7}}{2}$$

Whakawehea te -8\sqrt{7} ki te 2, kia riro ko -4\sqrt{7}.

$$-4\sqrt{7}$$
