Whakaoti i te f(t)=4t^2-12+4/t^2

$$f ( t ) = 4 t ^ { 2 } - 12 + \frac { 4 } { t ^ { 2 } }$$

Aromātai

$$4t^{2}-12+\frac{4}{t^{2}}$$

Ngā Hipanga Rongoā Poto

Hei tāpiri, hei tango kīanga rānei, me whakaroha ērā kia rite ā rātou tauraro. Whakareatia 4t^{2}-12 ki te \frac{t^{2}}{t^{2}}.

$$\frac{\left(4t^{2}-12\right)t^{2}}{t^{2}}+\frac{4}{t^{2}}$$

Tā te mea he rite te tauraro o \frac{\left(4t^{2}-12\right)t^{2}}{t^{2}} me \frac{4}{t^{2}}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{\left(4t^{2}-12\right)t^{2}+4}{t^{2}}$$

Mahia ngā whakarea i roto o \left(4t^{2}-12\right)t^{2}+4.

$$\frac{4t^{4}-12t^{2}+4}{t^{2}}$$

Tauwehe

$$\frac{4\left(t^{2}-\frac{3-\sqrt{5}}{2}\right)\left(t^{2}-\frac{\sqrt{5}+3}{2}\right)}{t^{2}}$$
