Whakaoti i te 1/1+x^4-2+1/1+x^2-4

$$\frac { 1 } { 1 + x ^ { 4 - 2 } } + \frac { 1 } { 1 + x ^ { 2 - 4 } }$$

Ngā Hipanga Rongoā Poto

Tangohia te 2 i te 4, ka 2.

$$\frac{1}{1+x^{2}}+\frac{1}{1+x^{2-4}}$$

Tangohia te 4 i te 2, ka -2.

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

Tauwehea te 1+x^{-2}.

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

Hei tāpiri, hei tango kīanga rānei, me whakaroha ērā kia rite ā rātou tauraro. Ko te taurea pātahi iti rawa o 1+x^{2} me x^{-2}\left(x^{2}+1\right) ko x^{-2}\left(x^{2}+1\right). Whakareatia \frac{1}{1+x^{2}} ki te \frac{x^{-2}}{x^{-2}}.

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

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

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

Me whakatauwehe ngā kīanga kāore anō i whakatauwehea i roto o \frac{x^{-2}+1}{x^{-2}\left(x^{2}+1\right)}.

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

Me whakakore tahi te x^{-2}\left(x^{2}+1\right) i te taurunga me te tauraro.
