\frac{\frac{\left(a+1\right)\left(a-1\right)}{a-1}-\frac{3}{a-1}}{\frac{a-2}{2a-2}}
Hei tāpiri, hei tango kīanga rānei, me whakaroha ērā kia rite ā rātou tauraro. Whakareatia a+1 ki te \frac{a-1}{a-1}.
\frac{\frac{\left(a+1\right)\left(a-1\right)-3}{a-1}}{\frac{a-2}{2a-2}}
Tā te mea he rite te tauraro o \frac{\left(a+1\right)\left(a-1\right)}{a-1} me \frac{3}{a-1}, me tango rāua mā te tango i ō raua taurunga.
\frac{\frac{a^{2}-a+a-1-3}{a-1}}{\frac{a-2}{2a-2}}
Mahia ngā whakarea i roto o \left(a+1\right)\left(a-1\right)-3.
\frac{\frac{a^{2}-4}{a-1}}{\frac{a-2}{2a-2}}
Whakakotahitia ngā kupu rite i a^{2}-a+a-1-3.
\frac{\left(a^{2}-4\right)\left(2a-2\right)}{\left(a-1\right)\left(a-2\right)}
Whakawehe \frac{a^{2}-4}{a-1} ki te \frac{a-2}{2a-2} mā te whakarea \frac{a^{2}-4}{a-1} ki te tau huripoki o \frac{a-2}{2a-2}.
\frac{2\left(a-2\right)\left(a-1\right)\left(a+2\right)}{\left(a-2\right)\left(a-1\right)}
Me whakatauwehe ngā kīanga kāore anō i whakatauwehea.
2\left(a+2\right)
Me whakakore tahi te \left(a-2\right)\left(a-1\right) i te taurunga me te tauraro.
2a+4
Me whakaroha te kīanga.
\frac{\frac{\left(a+1\right)\left(a-1\right)}{a-1}-\frac{3}{a-1}}{\frac{a-2}{2a-2}}
Hei tāpiri, hei tango kīanga rānei, me whakaroha ērā kia rite ā rātou tauraro. Whakareatia a+1 ki te \frac{a-1}{a-1}.
\frac{\frac{\left(a+1\right)\left(a-1\right)-3}{a-1}}{\frac{a-2}{2a-2}}
Tā te mea he rite te tauraro o \frac{\left(a+1\right)\left(a-1\right)}{a-1} me \frac{3}{a-1}, me tango rāua mā te tango i ō raua taurunga.
\frac{\frac{a^{2}-a+a-1-3}{a-1}}{\frac{a-2}{2a-2}}
Mahia ngā whakarea i roto o \left(a+1\right)\left(a-1\right)-3.
\frac{\frac{a^{2}-4}{a-1}}{\frac{a-2}{2a-2}}
Whakakotahitia ngā kupu rite i a^{2}-a+a-1-3.
\frac{\left(a^{2}-4\right)\left(2a-2\right)}{\left(a-1\right)\left(a-2\right)}
Whakawehe \frac{a^{2}-4}{a-1} ki te \frac{a-2}{2a-2} mā te whakarea \frac{a^{2}-4}{a-1} ki te tau huripoki o \frac{a-2}{2a-2}.
\frac{2\left(a-2\right)\left(a-1\right)\left(a+2\right)}{\left(a-2\right)\left(a-1\right)}
Me whakatauwehe ngā kīanga kāore anō i whakatauwehea.
2\left(a+2\right)
Me whakakore tahi te \left(a-2\right)\left(a-1\right) i te taurunga me te tauraro.
2a+4
Me whakaroha te kīanga.
