\frac{3z^{2}-12z-z+4-2z-8}{\left(z-4\right)\left(z+4\right)}
Mahia ngā whakarea i roto o \left(3z-1\right)\left(z-4\right)-2\left(z+4\right).
\frac{3z^{2}-15z-4}{\left(z-4\right)\left(z+4\right)}
Whakakotahitia ngā kupu rite i 3z^{2}-12z-z+4-2z-8.
\frac{3z^{2}-15z-4}{z^{2}-16}
Whakarohaina te \left(z-4\right)\left(z+4\right).
