\frac{x-2}{x+2}-1
Whakawehea te x-2 ki te x-2, kia riro ko 1.
\frac{x-2}{x+2}-\frac{x+2}{x+2}
Hei tāpiri, hei tango kīanga rānei, me whakaroha ērā kia rite ā rātou tauraro. Whakareatia 1 ki te \frac{x+2}{x+2}.
\frac{x-2-\left(x+2\right)}{x+2}
Tā te mea he rite te tauraro o \frac{x-2}{x+2} me \frac{x+2}{x+2}, me tango rāua mā te tango i ō raua taurunga.
\frac{x-2-x-2}{x+2}
Mahia ngā whakarea i roto o x-2-\left(x+2\right).
\frac{-4}{x+2}
Whakakotahitia ngā kupu rite i x-2-x-2.
\frac{x-2}{x+2}-1
Whakawehea te x-2 ki te x-2, kia riro ko 1.
\frac{x-2}{x+2}-\frac{x+2}{x+2}
Hei tāpiri, hei tango kīanga rānei, me whakaroha ērā kia rite ā rātou tauraro. Whakareatia 1 ki te \frac{x+2}{x+2}.
\frac{x-2-\left(x+2\right)}{x+2}
Tā te mea he rite te tauraro o \frac{x-2}{x+2} me \frac{x+2}{x+2}, me tango rāua mā te tango i ō raua taurunga.
\frac{x-2-x-2}{x+2}
Mahia ngā whakarea i roto o x-2-\left(x+2\right).
\frac{-4}{x+2}
Whakakotahitia ngā kupu rite i x-2-x-2.
