Whakaoti i te 9a^2-(a+7^2/4a^2+7a

$$\frac{ 9 { a }^{ 2 } -(a+ { 7 }^{ 2 } }{ 4 { a }^{ 2 } +7a }$$

Aromātai

$$\frac{36a^{4}+63a^{3}-a-49}{a\left(4a+7\right)}$$

Ngā Hipanga Rongoā Poto

Tātaihia te 7 mā te pū o 2, kia riro ko 49.

$$9a^{2}-\frac{a+49}{4a^{2}+7a}$$

Tauwehea te 4a^{2}+7a.

$$9a^{2}-\frac{a+49}{a\left(4a+7\right)}$$

Hei tāpiri, hei tango kīanga rānei, me whakaroha ērā kia rite ā rātou tauraro. Whakareatia 9a^{2} ki te \frac{a\left(4a+7\right)}{a\left(4a+7\right)}.

$$\frac{9a^{2}a\left(4a+7\right)}{a\left(4a+7\right)}-\frac{a+49}{a\left(4a+7\right)}$$

Tā te mea he rite te tauraro o \frac{9a^{2}a\left(4a+7\right)}{a\left(4a+7\right)} me \frac{a+49}{a\left(4a+7\right)}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{9a^{2}a\left(4a+7\right)-\left(a+49\right)}{a\left(4a+7\right)}$$

Mahia ngā whakarea i roto o 9a^{2}a\left(4a+7\right)-\left(a+49\right).

$$\frac{36a^{4}+63a^{3}-a-49}{a\left(4a+7\right)}$$

Whakarohaina te a\left(4a+7\right).
