Whakaoti i te f(x)=x^3-3x^2-45x+2

$$f ( x ) = x ^ { 3 } - 3 x ^ { 2 } - 45 x + 2$$

Kimi Pārōnaki e ai ki x

$$3\left(x-5\right)\left(x+3\right)$$

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}.

$$3x^{3-1}+2\left(-3\right)x^{2-1}-45x^{1-1}$$

Tango 1 mai i 3.

$$3x^{2}+2\left(-3\right)x^{2-1}-45x^{1-1}$$

Whakareatia 2 ki te -3.

$$3x^{2}-6x^{2-1}-45x^{1-1}$$

Tango 1 mai i 2.

$$3x^{2}-6x^{1}-45x^{1-1}$$

Tango 1 mai i 1.

$$3x^{2}-6x^{1}-45x^{0}$$

Mō tētahi kupu t, t^{1}=t.

$$3x^{2}-6x-45x^{0}$$

Mō tētahi kupu t mahue te 0, t^{0}=1.

$$3x^{2}-6x-45$$

Aromātai

$$x^{3}-3x^{2}-45x+2$$
