$$\frac { a } { a + 1 } - \frac { a ^ { 2 } } { a ^ { 2 } - 1 }$$

Aromātai

$$-\frac{a}{a^{2}-1}$$

Ngā Hipanga Rongoā Poto

Tauwehea te a^{2}-1.

$$\frac{a}{a+1}-\frac{a^{2}}{\left(a-1\right)\left(a+1\right)}$$

Hei tāpiri, hei tango kīanga rānei, me whakaroha ērā kia rite ā rātou tauraro. Ko te taurea pātahi iti rawa o a+1 me \left(a-1\right)\left(a+1\right) ko \left(a-1\right)\left(a+1\right). Whakareatia \frac{a}{a+1} ki te \frac{a-1}{a-1}.

$$\frac{a\left(a-1\right)}{\left(a-1\right)\left(a+1\right)}-\frac{a^{2}}{\left(a-1\right)\left(a+1\right)}$$

Tā te mea he rite te tauraro o \frac{a\left(a-1\right)}{\left(a-1\right)\left(a+1\right)} me \frac{a^{2}}{\left(a-1\right)\left(a+1\right)}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{a\left(a-1\right)-a^{2}}{\left(a-1\right)\left(a+1\right)}$$

Mahia ngā whakarea i roto o a\left(a-1\right)-a^{2}.

$$\frac{a^{2}-a-a^{2}}{\left(a-1\right)\left(a+1\right)}$$

Whakakotahitia ngā kupu rite i a^{2}-a-a^{2}.

$$\frac{-a}{\left(a-1\right)\left(a+1\right)}$$

Whakarohaina te \left(a-1\right)\left(a+1\right).

$$\frac{-a}{a^{2}-1}$$

Tauwehe
