Whakaoti i te a^3-4a^2+2a-1

$$a ^ { 3 } - 4 a ^ { 2 } + 2 a - 1$$

Kimi Pārōnaki e ai ki a

$$3a^{2}-8a+2$$

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

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}.

$$3a^{3-1}+2\left(-4\right)a^{2-1}+2a^{1-1}$$

Tango 1 mai i 3.

$$3a^{2}+2\left(-4\right)a^{2-1}+2a^{1-1}$$

Whakareatia 2 ki te -4.

$$3a^{2}-8a^{2-1}+2a^{1-1}$$

Tango 1 mai i 2.

$$3a^{2}-8a^{1}+2a^{1-1}$$

Tango 1 mai i 1.

$$3a^{2}-8a^{1}+2a^{0}$$

Mō tētahi kupu t, t^{1}=t.

$$3a^{2}-8a+2a^{0}$$

Mō tētahi kupu t mahue te 0, t^{0}=1.

$$3a^{2}-8a+2\times 1$$

Mō tētahi kupu t, t\times 1=t me 1t=t.
