Whakaoti i te x=3.2divx

$$x=3.2 \div x$$

Whakaoti mō x

$$x = \frac{4 \sqrt{5}}{5} \approx 1.788854382$$

$$x = -\frac{4 \sqrt{5}}{5} \approx -1.788854382$$

Ngā Upane mā te Kimi Pūtakerua

Tangohia te \frac{3.2}{x} mai i ngā taha e rua.

$$x-\frac{3.2}{x}=0$$

Tē taea kia ōrite te tāupe x ki 0 nā te kore tautuhi i te whakawehenga mā te kore. Whakareatia ngā taha e rua o te whārite ki te x.

$$xx-3.2=0$$

Whakareatia te x ki te x, ka x^{2}.

$$x^{2}-3.2=0$$

Me tāpiri te 3.2 ki ngā taha e rua. Ko te tau i tāpiria he kore ka hua koia tonu.

$$x^{2}=3.2$$

Tuhia te pūtakerua o ngā taha e rua o te whārite.

$$x=\frac{4\sqrt{5}}{5} x=-\frac{4\sqrt{5}}{5}$$

Ngā Upane e Whakamahi ana i te Tikanga Tātai Pūrua

Tangohia te \frac{3.2}{x} mai i ngā taha e rua.

$$x-\frac{3.2}{x}=0$$

Tē taea kia ōrite te tāupe x ki 0 nā te kore tautuhi i te whakawehenga mā te kore. Whakareatia ngā taha e rua o te whārite ki te x.

$$xx-3.2=0$$

Whakareatia te x ki te x, ka x^{2}.

$$x^{2}-3.2=0$$

Kei te āhua arowhānui tēnei whārite: ax^{2}+bx+c=0. Me whakakapi 1 mō a, 0 mō b, me -3.2 mō c i te tikanga tātai pūrua, \frac{-b±\sqrt{b^{2}-4ac}}{2a}.

$$x=\frac{0±\sqrt{0^{2}-4\left(-3.2\right)}}{2}$$

Pūrua 0.

$$x=\frac{0±\sqrt{-4\left(-3.2\right)}}{2}$$

Whakareatia -4 ki te -3.2.

$$x=\frac{0±\sqrt{12.8}}{2}$$

Tuhia te pūtakerua o te 12.8.

$$x=\frac{0±\frac{8\sqrt{5}}{5}}{2}$$

Nā, me whakaoti te whārite x=\frac{0±\frac{8\sqrt{5}}{5}}{2} ina he tāpiri te ±.

$$x=\frac{4\sqrt{5}}{5}$$

Nā, me whakaoti te whārite x=\frac{0±\frac{8\sqrt{5}}{5}}{2} ina he tango te ±.

$$x=-\frac{4\sqrt{5}}{5}$$

Kua oti te whārite te whakatau.

$$x=\frac{4\sqrt{5}}{5} x=-\frac{4\sqrt{5}}{5}$$
