3\left(c^{2}+2c\right)
Tauwehea te 3.
c\left(c+2\right)
Whakaarohia te c^{2}+2c. Tauwehea te c.
3c\left(c+2\right)
Me tuhi anō te kīanga whakatauwehe katoa.
3c^{2}+6c=0
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.
c=\frac{-6±\sqrt{6^{2}}}{2\times 3}
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.
c=\frac{-6±6}{2\times 3}
Tuhia te pūtakerua o te 6^{2}.
c=\frac{-6±6}{6}
Whakareatia 2 ki te 3.
c=\frac{0}{6}
Nā, me whakaoti te whārite c=\frac{-6±6}{6} ina he tāpiri te ±. Tāpiri -6 ki te 6.
c=0
Whakawehe 0 ki te 6.
c=-\frac{12}{6}
Nā, me whakaoti te whārite c=\frac{-6±6}{6} ina he tango te ±. Tango 6 mai i -6.
c=-2
Whakawehe -12 ki te 6.
3c^{2}+6c=3c\left(c-\left(-2\right)\right)
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}.
3c^{2}+6c=3c\left(c+2\right)
Whakamāmātia ngā kīanga katoa o te āhua p-\left(-q\right) ki te p+q.
