Whakaoti i te -1/left(2-yright)^2-1/y^2

$$\frac{ -1 }{ { \left(2-y \right) }^{ 2 } } - \frac{ 1 }{ { y }^{ 2 } }$$

Aromātai

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

Ngā Hipanga Rongoā Poto

Hei tāpiri, hei tango kīanga rānei, me whakaroha ērā kia rite ā rātou tauraro. Ko te taurea pātahi iti rawa o \left(2-y\right)^{2} me y^{2} ko y^{2}\left(-y+2\right)^{2}. Whakareatia \frac{-1}{\left(2-y\right)^{2}} ki te \frac{y^{2}}{y^{2}}. Whakareatia \frac{1}{y^{2}} ki te \frac{\left(-y+2\right)^{2}}{\left(-y+2\right)^{2}}.

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

Tā te mea he rite te tauraro o \frac{-y^{2}}{y^{2}\left(-y+2\right)^{2}} me \frac{\left(-y+2\right)^{2}}{y^{2}\left(-y+2\right)^{2}}, me tango rāua mā te tango i ō raua taurunga.

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

Mahia ngā whakarea i roto o -y^{2}-\left(-y+2\right)^{2}.

$$\frac{-y^{2}-y^{2}+4y-4}{y^{2}\left(-y+2\right)^{2}}$$

Whakakotahitia ngā kupu rite i -y^{2}-y^{2}+4y-4.

$$\frac{-2y^{2}+4y-4}{y^{2}\left(-y+2\right)^{2}}$$

Whakarohaina te y^{2}\left(-y+2\right)^{2}.

$$\frac{-2y^{2}+4y-4}{y^{4}-4y^{3}+4y^{2}}$$

Whakaroha

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