Whakaoti i te (3t^2-2t-1)+(4t^2-7t+6)

$$( 3 t ^ { 2 } - 2 t - 1 ) + ( 4 t ^ { 2 } - 7 t + 6 )$$

Aromātai

$$7t^{2}-9t+5$$

Ngā Upane Otinga

Pahekotia te 3t^{2} me 4t^{2}, ka 7t^{2}.

$$7t^{2}-2t-1-7t+6$$

Pahekotia te -2t me -7t, ka -9t.

$$7t^{2}-9t-1+6$$

Tāpirihia te -1 ki te 6, ka 5.

$$7t^{2}-9t+5$$

Kimi Pārōnaki e ai ki t

$$14t-9$$

Ngā Upane e Whakamahi ana i te Ture Pārōnaki mō te Tapeke

Pahekotia te 3t^{2} me 4t^{2}, ka 7t^{2}.

$$\frac{\mathrm{d}}{\mathrm{d}t}(7t^{2}-2t-1-7t+6)$$

Pahekotia te -2t me -7t, ka -9t.

$$\frac{\mathrm{d}}{\mathrm{d}t}(7t^{2}-9t-1+6)$$

Tāpirihia te -1 ki te 6, ka 5.

$$\frac{\mathrm{d}}{\mathrm{d}t}(7t^{2}-9t+5)$$

Ko te pārōnaki o tētahi pūrau ko te tapeke o ngā pārōnaki o ōna kīanga tau. Ko te pārōnaki o tētahi kīanga tau pūmau ko 0. Ko te pārōnaki o te ax^{n} ko te nax^{n-1}.

$$2\times 7t^{2-1}-9t^{1-1}$$

Whakareatia 2 ki te 7.

$$14t^{2-1}-9t^{1-1}$$

Tango 1 mai i 2.

$$14t^{1}-9t^{1-1}$$

Tango 1 mai i 1.

$$14t^{1}-9t^{0}$$

Mō tētahi kupu t, t^{1}=t.

$$14t-9t^{0}$$

Mō tētahi kupu t mahue te 0, t^{0}=1.
