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

Resta \frac{1}{2\left(z+1\right)} de \frac{1}{2\left(z+1\right)} para obter 0.

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

Para sumar ou restar expresións, expándeas para facer que os seus denominadores sexan iguais. O mínimo común múltiplo de 2\left(z-1\right) e 2\left(z-1\right)^{2} é 2\left(z-1\right)^{2}. Multiplica -\frac{1}{2\left(z-1\right)} por \frac{z-1}{z-1}.

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

Dado que -\frac{z-1}{2\left(z-1\right)^{2}} e \frac{1}{2\left(z-1\right)^{2}} teñen o mesmo denominador, réstaos mediante a resta dos seus numeradores.

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

Fai as multiplicacións en -\left(z-1\right)-1.

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

Combina como termos en -z+1-1.

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

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