Kua tāruatia ki te papatopenga
\frac{-3A^{2}}{A\left(A+9\right)}+3
Me whakatauwehe ngā kīanga kāore anō i whakatauwehea i roto o \frac{-3A^{2}}{A^{2}+9A}.
\frac{-3A}{A+9}+3
Me whakakore tahi te A i te taurunga me te tauraro.
\frac{-3A}{A+9}+\frac{3\left(A+9\right)}{A+9}
Hei tāpiri, hei tango kīanga rānei, me whakaroha ērā kia rite ā rātou tauraro. Whakareatia 3 ki te \frac{A+9}{A+9}.
\frac{-3A+3\left(A+9\right)}{A+9}
Tā te mea he rite te tauraro o \frac{-3A}{A+9} me \frac{3\left(A+9\right)}{A+9}, me tāpiri rāua mā te tāpiri i ō raua taurunga.
