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

Tangohia te \frac{1}{2\left(z+1\right)} i te \frac{1}{2\left(z+1\right)}, ka 0.

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

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

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

Tā te mea he rite te tauraro o -\frac{z-1}{2\left(z-1\right)^{2}} me \frac{1}{2\left(z-1\right)^{2}}, me tango rāua mā te tango i ō raua taurunga.

\frac{-z+1-1}{2\left(z-1\right)^{2}}

Mahia ngā whakarea i roto o -\left(z-1\right)-1.

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

Whakakotahitia ngā kupu rite i -z+1-1.

\frac{-z}{2z^{2}-4z+2}

Whakarohaina te 2\left(z-1\right)^{2}.

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

Tangohia te \frac{1}{2\left(z+1\right)} i te \frac{1}{2\left(z+1\right)}, ka 0.

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

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