Whakaoti i te f(-3)=(-3)^3-2(-3)^2/(-3)^2-4

$$f ( - 3 ) = \frac { ( - 3 ) ^ { 3 } - 2 ( - 3 ) ^ { 2 } } { ( - 3 ) ^ { 2 } - 4 }$$

Tātaihia te -3 mā te pū o 3, kia riro ko -27.

$$\frac{-27-2\left(-3\right)^{2}}{\left(-3\right)^{2}-4}$$

Tātaihia te -3 mā te pū o 2, kia riro ko 9.

$$\frac{-27-2\times 9}{\left(-3\right)^{2}-4}$$

Whakareatia te 2 ki te 9, ka 18.

$$\frac{-27-18}{\left(-3\right)^{2}-4}$$

Tangohia te 18 i te -27, ka -45.

$$\frac{-45}{\left(-3\right)^{2}-4}$$

Tātaihia te -3 mā te pū o 2, kia riro ko 9.

$$\frac{-45}{9-4}$$

Tangohia te 4 i te 9, ka 5.

$$\frac{-45}{5}$$

Whakawehea te -45 ki te 5, kia riro ko -9.
