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

Resteu \frac{1}{2\left(z+1\right)} de \frac{1}{2\left(z+1\right)} per obtenir 0.

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

Per afegir o restar les expressions, amplieu-les perquè els denominadors coincideixin. El mínim comú múltiple de 2\left(z-1\right) i 2\left(z-1\right)^{2} és 2\left(z-1\right)^{2}. Multipliqueu -\frac{1}{2\left(z-1\right)} per \frac{z-1}{z-1}.

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

Com que -\frac{z-1}{2\left(z-1\right)^{2}} i \frac{1}{2\left(z-1\right)^{2}} tenen el mateix denominador, resteu-los mitjançant la subtracció dels seus numeradors.

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

Feu les multiplicacions a -\left(z-1\right)-1.

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

Combineu els termes similars de -z+1-1.

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

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