\frac{w^{2}-\left(21w-108\right)}{w-9}
Tā te mea he rite te tauraro o \frac{w^{2}}{w-9} me \frac{21w-108}{w-9}, me tango rāua mā te tango i ō raua taurunga.
\frac{w^{2}-21w+108}{w-9}
Mahia ngā whakarea i roto o w^{2}-\left(21w-108\right).
\frac{\left(w-12\right)\left(w-9\right)}{w-9}
Me whakatauwehe ngā kīanga kāore anō i whakatauwehea i roto o \frac{w^{2}-21w+108}{w-9}.
