Kua tāruatia ki te papatopenga
\frac{\left(z^{2}-4z-21\right)\left(z-3\right)}{\left(z+8\right)\left(z-7\right)}
Me whakarea te \frac{z^{2}-4z-21}{z+8} ki te \frac{z-3}{z-7} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.
\frac{\left(z-7\right)\left(z-3\right)\left(z+3\right)}{\left(z-7\right)\left(z+8\right)}
Me whakatauwehe ngā kīanga kāore anō i whakatauwehea.
\frac{\left(z-3\right)\left(z+3\right)}{z+8}
Me whakakore tahi te z-7 i te taurunga me te tauraro.
\frac{z^{2}-9}{z+8}
Me whakaroha te kīanga.
\frac{\left(z^{2}-4z-21\right)\left(z-3\right)}{\left(z+8\right)\left(z-7\right)}
Me whakarea te \frac{z^{2}-4z-21}{z+8} ki te \frac{z-3}{z-7} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.
\frac{\left(z-7\right)\left(z-3\right)\left(z+3\right)}{\left(z-7\right)\left(z+8\right)}
Me whakatauwehe ngā kīanga kāore anō i whakatauwehea.
\frac{\left(z-3\right)\left(z+3\right)}{z+8}
Me whakakore tahi te z-7 i te taurunga me te tauraro.
\frac{z^{2}-9}{z+8}
