Kua tāruatia ki te papatopenga
\frac{x-3}{\left(x-2\right)\left(x+2\right)}-\frac{5}{x+2}
Tauwehea te x^{2}-4.
\frac{x-3}{\left(x-2\right)\left(x+2\right)}-\frac{5\left(x-2\right)}{\left(x-2\right)\left(x+2\right)}
Hei tāpiri, hei tango kīanga rānei, me whakaroha ērā kia rite ā rātou tauraro. Ko te taurea pātahi iti rawa o \left(x-2\right)\left(x+2\right) me x+2 ko \left(x-2\right)\left(x+2\right). Whakareatia \frac{5}{x+2} ki te \frac{x-2}{x-2}.
\frac{x-3-5\left(x-2\right)}{\left(x-2\right)\left(x+2\right)}
Tā te mea he rite te tauraro o \frac{x-3}{\left(x-2\right)\left(x+2\right)} me \frac{5\left(x-2\right)}{\left(x-2\right)\left(x+2\right)}, me tango rāua mā te tango i ō raua taurunga.
\frac{x-3-5x+10}{\left(x-2\right)\left(x+2\right)}
Mahia ngā whakarea i roto o x-3-5\left(x-2\right).
\frac{-4x+7}{\left(x-2\right)\left(x+2\right)}
Whakakotahitia ngā kupu rite i x-3-5x+10.
\frac{-4x+7}{x^{2}-4}
Whakarohaina te \left(x-2\right)\left(x+2\right).
\frac{x-3}{\left(x-2\right)\left(x+2\right)}-\frac{5}{x+2}
Tauwehea te x^{2}-4.
