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

Oduzmite \frac{1}{2\left(z+1\right)} od \frac{1}{2\left(z+1\right)} da biste dobili 0.

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

Da biste izvršili zbrajanje ili oduzimanje izraza, rastavite ih kako bi im nazivnici bili isti. Najmanji zajednički množilac brojeva 2\left(z-1\right) i 2\left(z-1\right)^{2} je 2\left(z-1\right)^{2}. Pomnožite -\frac{1}{2\left(z-1\right)} i \frac{z-1}{z-1}.

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

Pošto -\frac{z-1}{2\left(z-1\right)^{2}} i \frac{1}{2\left(z-1\right)^{2}} imaju isti imenilac, oduzmite ih tako što ćete oduzeti njihove brojioce.

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

Izvršite množenja u -\left(z-1\right)-1.

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

Kombinirajte slične izraze u -z+1-1.

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

Proširite 2\left(z-1\right)^{2}.

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

Oduzmite \frac{1}{2\left(z+1\right)} od \frac{1}{2\left(z+1\right)} da biste dobili 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}}
