Whakaoti i te 3/m^2-14m+49+2m/7-m

$$\frac { 3 } { m ^ { 2 } - 14 m + 49 } + \frac { 2 m } { 7 - m }$$

Aromātai

$$-\frac{2m^{2}-14m-3}{\left(7-m\right)^{2}}$$

Ngā Hipanga Rongoā Poto

Tauwehea te m^{2}-14m+49.

$$\frac{3}{\left(m-7\right)^{2}}+\frac{2m}{7-m}$$

Hei tāpiri, hei tango kīanga rānei, me whakaroha ērā kia rite ā rātou tauraro. Ko te taurea pātahi iti rawa o \left(m-7\right)^{2} me 7-m ko \left(m-7\right)^{2}. Whakareatia \frac{2m}{7-m} ki te \frac{-\left(m-7\right)}{-\left(m-7\right)}.

$$\frac{3}{\left(m-7\right)^{2}}+\frac{2m\left(-1\right)\left(m-7\right)}{\left(m-7\right)^{2}}$$

Tā te mea he rite te tauraro o \frac{3}{\left(m-7\right)^{2}} me \frac{2m\left(-1\right)\left(m-7\right)}{\left(m-7\right)^{2}}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{3+2m\left(-1\right)\left(m-7\right)}{\left(m-7\right)^{2}}$$

Mahia ngā whakarea i roto o 3+2m\left(-1\right)\left(m-7\right).

$$\frac{3-2m^{2}+14m}{\left(m-7\right)^{2}}$$

Whakarohaina te \left(m-7\right)^{2}.

$$\frac{3-2m^{2}+14m}{m^{2}-14m+49}$$
