Whakaoti i te 10-x^2-5x^4-2x

$$10- { x }^{ 2 } -5 { x }^{ 4 } -2x$$

Kimi Pārōnaki e ai ki x

$$-20x^{3}-2x-2$$

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}.

$$2\left(-1\right)x^{2-1}+4\left(-5\right)x^{4-1}-2x^{1-1}$$

Whakareatia 2 ki te -1.

$$-2x^{2-1}+4\left(-5\right)x^{4-1}-2x^{1-1}$$

Tango 1 mai i 2.

$$-2x^{1}+4\left(-5\right)x^{4-1}-2x^{1-1}$$

Whakareatia 4 ki te -5.

$$-2x^{1}-20x^{4-1}-2x^{1-1}$$

Tango 1 mai i 4.

$$-2x^{1}-20x^{3}-2x^{1-1}$$

Tango 1 mai i 1.

$$-2x^{1}-20x^{3}-2x^{0}$$

Mō tētahi kupu t, t^{1}=t.

$$-2x-20x^{3}-2x^{0}$$

Mō tētahi kupu t mahue te 0, t^{0}=1.

$$-2x-20x^{3}-2$$
