Whakaoti i te 6x-3x^2

$$6 x - 3 x ^ { 2 }$$

Tauwehe

$$3x\left(2-x\right)$$

Ngā Upane Otinga

Tauwehea te 3.

$$3\left(2x-x^{2}\right)$$

Whakaarohia te 2x-x^{2}. Tauwehea te x.

$$x\left(2-x\right)$$

Me tuhi anō te kīanga whakatauwehe katoa.

$$3x\left(-x+2\right)$$

Ngā Upane e Whakamahi ana i te Tikanga Tātai Pūrua

Ka taea te huamaha pūrua te tauwehe mā te whakamahi i te huringa ax^{2}+bx+c=a\left(x-x_{1}\right)\left(x-x_{2}\right), ina ko x_{1} me x_{2} ngā otinga o te whārite pūrua ax^{2}+bx+c=0.

$$-3x^{2}+6x=0$$

Ko ngā whārite katoa o te āhua ax^{2}+bx+c=0 ka taea te whakaoti mā te whakamahi i te tikanga tātai pūrua: \frac{-b±\sqrt{b^{2}-4ac}}{2a}. E rua ngā otinga ka puta i te tikanga tātai pūrua, ko tētahi ina he tāpiri a ±, ā, ko tētahi ina he tango.

$$x=\frac{-6±\sqrt{6^{2}}}{2\left(-3\right)}$$

Tuhia te pūtakerua o te 6^{2}.

$$x=\frac{-6±6}{2\left(-3\right)}$$

Whakareatia 2 ki te -3.

$$x=\frac{-6±6}{-6}$$

Nā, me whakaoti te whārite x=\frac{-6±6}{-6} ina he tāpiri te ±. Tāpiri -6 ki te 6.

$$x=\frac{0}{-6}$$

Whakawehe 0 ki te -6.

$$x=0$$

Nā, me whakaoti te whārite x=\frac{-6±6}{-6} ina he tango te ±. Tango 6 mai i -6.

$$x=-\frac{12}{-6}$$

Whakawehe -12 ki te -6.

$$x=2$$

Tauwehea te kīanga taketake mā te whakamahi i te ax^{2}+bx+c=a\left(x-x_{1}\right)\left(x-x_{2}\right). Me whakakapi te 0 mō te x_{1} me te 2 mō te x_{2}.

$$-3x^{2}+6x=-3x\left(x-2\right)$$

Aromātai

$$3x\left(2-x\right)$$
