Whakaoti i te a-2/a+2-a^2/b

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

Aromātai

$$\frac{-a^{3}-2a^{2}+ab-2b}{b\left(a+2\right)}$$

Hei tāpiri, hei tango kīanga rānei, me whakaroha ērā kia rite ā rātou tauraro. Ko te taurea pātahi iti rawa o a+2 me b ko b\left(a+2\right). Whakareatia \frac{a-2}{a+2} ki te \frac{b}{b}. Whakareatia \frac{a^{2}}{b} ki te \frac{a+2}{a+2}.

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

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

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

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

$$\frac{ab-2b-a^{3}-2a^{2}}{b\left(a+2\right)}$$

Whakarohaina te b\left(a+2\right).

$$\frac{ab-2b-a^{3}-2a^{2}}{ab+2b}$$
