\frac{\left(z-b\right)\left(z+1\right)}{\left(z-1\right)\left(z+4\right)}
Immultiplika \frac{z-b}{z-1} b'\frac{z+1}{z+4} billi timmultiplika n-numeratur bin-numeratur u d-denominatur bid-denominatur.
\frac{z^{2}+z-bz-b}{\left(z-1\right)\left(z+4\right)}
Applika l-propjetà distributtiva billi timmultiplika kull terminu ta' z-b b'kull terminu ta' z+1.
\frac{z^{2}+z-bz-b}{z^{2}+4z-z-4}
Applika l-propjetà distributtiva billi timmultiplika kull terminu ta' z-1 b'kull terminu ta' z+4.
\frac{z^{2}+z-bz-b}{z^{2}+3z-4}
Ikkombina 4z u -z biex tikseb 3z.
