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

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

Aromātai

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

Ngā Hipanga Rongoā Poto

Tauwehea te x^{2}-4. Tauwehea te 2x-4.

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

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 2\left(x-2\right) ko 2\left(x-2\right)\left(x+2\right). Whakareatia \frac{x}{\left(x-2\right)\left(x+2\right)} ki te \frac{2}{2}. Whakareatia \frac{1}{2\left(x-2\right)} ki te \frac{x+2}{x+2}.

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

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

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

Mahia ngā whakarea i roto o 2x-\left(x+2\right).

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

Whakakotahitia ngā kupu rite i 2x-x-2.

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

Me whakakore tahi te x-2 i te taurunga me te tauraro.

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

Whakarohaina te 2\left(x+2\right).

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

Tauwehe

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