Whakaoti i te 4x^2+1-2x2^n+1

$$4 x ^ { 2 } + 1 - 2 x 2 ^ { n + 1 }$$

Kimi Pārōnaki e ai ki x

$$8x-4\times 2^{n}$$

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}.

$$2\times 4x^{2-1}+\left(-2\times 2^{n+1}\right)x^{1-1}$$

Whakareatia 2 ki te 4.

$$8x^{2-1}+\left(-2\times 2^{n+1}\right)x^{1-1}$$

Tango 1 mai i 2.

$$8x^{1}+\left(-2\times 2^{n+1}\right)x^{1-1}$$

Tango 1 mai i 1.

$$8x^{1}+\left(-4\times 2^{n}\right)x^{0}$$

Mō tētahi kupu t, t^{1}=t.

$$8x+\left(-4\times 2^{n}\right)x^{0}$$

Mō tētahi kupu t mahue te 0, t^{0}=1.

$$8x+\left(-4\times 2^{n}\right)\times 1$$

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

$$8x-4\times 2^{n}$$

Aromātai

$$4x^{2}-4x\times 2^{n}+1$$
