Whakaoti i te -f*-6*06=1/2*06*10*03-1/2*06*16

$$- f \cdot - 6 \times 06 = \frac { 1 } { 2 } \times 06 \times 10 \times 03 - \frac { 1 } { 2 } \times 06 \times 16$$

Whakaoti mō f

$$f\in \mathrm{R}$$

Ngā Upane Otinga

Whakareatia te -6 ki te 0, ka 0.

$$\left(-f\right)\times 0\times 6=\frac{1}{2}\times 0\times 6\times 10\times 0\times 3-\frac{1}{2}\times 0\times 6\times 16$$

Whakareatia te 0 ki te 6, ka 0.

$$\left(-f\right)\times 0=\frac{1}{2}\times 0\times 6\times 10\times 0\times 3-\frac{1}{2}\times 0\times 6\times 16$$

Ko te tau i whakarea ki te kore ka hua ko te kore.

$$0=\frac{1}{2}\times 0\times 6\times 10\times 0\times 3-\frac{1}{2}\times 0\times 6\times 16$$

Whakareatia te \frac{1}{2} ki te 0, ka 0.

$$0=0\times 6\times 10\times 0\times 3-\frac{1}{2}\times 0\times 6\times 16$$

Whakareatia te 0 ki te 6, ka 0.

$$0=0\times 10\times 0\times 3-\frac{1}{2}\times 0\times 6\times 16$$

Whakareatia te 0 ki te 10, ka 0.

$$0=0\times 0\times 3-\frac{1}{2}\times 0\times 6\times 16$$

Whakareatia te 0 ki te 0, ka 0.

$$0=0\times 3-\frac{1}{2}\times 0\times 6\times 16$$

Whakareatia te 0 ki te 3, ka 0.

$$0=0-\frac{1}{2}\times 0\times 6\times 16$$

Whakareatia te \frac{1}{2} ki te 0, ka 0.

$$0=0-0\times 6\times 16$$

Whakareatia te 0 ki te 6, ka 0.

$$0=0-0\times 16$$

Whakareatia te 0 ki te 16, ka 0.

$$0=0-0$$

Mā te tango i te 0 i a ia ake anō ka toe ko te 0.

$$0=0$$

Whakatauritea te 0 me te 0.

He pono tēnei mō tētahi f ahakoa.
