Whakaoti i te -36ydiv12+18div(-27y)

$$- 36 y \div 12 + 18 \div ( - 27 y )$$

Aromātai

$$-3y-\frac{2}{3y}$$

Ngā Hipanga Rongoā Poto

Whakawehea te -36y ki te 12, kia riro ko -3y.

$$-3y+\frac{18}{-27y}$$

Hei tāpiri, hei tango kīanga rānei, me whakaroha ērā kia rite ā rātou tauraro. Whakareatia -3y ki te \frac{-27y}{-27y}.

$$\frac{-3y\left(-27\right)y}{-27y}+\frac{18}{-27y}$$

Tā te mea he rite te tauraro o \frac{-3y\left(-27\right)y}{-27y} me \frac{18}{-27y}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{-3y\left(-27\right)y+18}{-27y}$$

Mahia ngā whakarea i roto o -3y\left(-27\right)y+18.

$$\frac{81y^{2}+18}{-27y}$$

Me whakatauwehe ngā kīanga kāore anō i whakatauwehea i roto o \frac{81y^{2}+18}{-27y}.

$$\frac{9\left(9y^{2}+2\right)}{-27y}$$

Me whakakore tahi te 9 i te taurunga me te tauraro.

$$\frac{9y^{2}+2}{-3y}$$

Tauwehe

$$\frac{-9y^{2}-2}{3y}$$
