Whakaoti i te 7/x^2-4-5/x^2+4x+4

$$\frac { 7 } { x ^ { 2 } - 4 } - \frac { 5 } { x ^ { 2 } + 4 x + 4 }$$

Aromātai

$$\frac{2\left(x+12\right)}{\left(x-2\right)\left(x+2\right)^{2}}$$

Ngā Hipanga Rongoā Poto

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

$$\frac{7}{\left(x-2\right)\left(x+2\right)}-\frac{5}{\left(x+2\right)^{2}}$$

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 \left(x+2\right)^{2} ko \left(x-2\right)\left(x+2\right)^{2}. Whakareatia \frac{7}{\left(x-2\right)\left(x+2\right)} ki te \frac{x+2}{x+2}. Whakareatia \frac{5}{\left(x+2\right)^{2}} ki te \frac{x-2}{x-2}.

$$\frac{7\left(x+2\right)}{\left(x-2\right)\left(x+2\right)^{2}}-\frac{5\left(x-2\right)}{\left(x-2\right)\left(x+2\right)^{2}}$$

Tā te mea he rite te tauraro o \frac{7\left(x+2\right)}{\left(x-2\right)\left(x+2\right)^{2}} me \frac{5\left(x-2\right)}{\left(x-2\right)\left(x+2\right)^{2}}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{7\left(x+2\right)-5\left(x-2\right)}{\left(x-2\right)\left(x+2\right)^{2}}$$

Mahia ngā whakarea i roto o 7\left(x+2\right)-5\left(x-2\right).

$$\frac{7x+14-5x+10}{\left(x-2\right)\left(x+2\right)^{2}}$$

Whakakotahitia ngā kupu rite i 7x+14-5x+10.

$$\frac{2x+24}{\left(x-2\right)\left(x+2\right)^{2}}$$

Whakarohaina te \left(x-2\right)\left(x+2\right)^{2}.

$$\frac{2x+24}{x^{3}+2x^{2}-4x-8}$$

Kimi Pārōnaki e ai ki x

$$-\frac{\left(2x+17\right)^{2}-329}{\left(x-2\right)^{2}\left(x+2\right)^{3}}$$
