Whakaoti i te 7-2x+x^3-x^2+x

$$7 - 2 x + x ^ { 3 } - x ^ { 2 } + x$$

Kimi Pārōnaki e ai ki x

$$\left(x-1\right)\left(3x+1\right)$$

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

Pahekotia te -2x me x, ka -x.

$$\frac{\mathrm{d}}{\mathrm{d}x}(7-x+x^{3}-x^{2})$$

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}.

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

Tango 1 mai i 1.

$$-x^{0}+3x^{3-1}+2\left(-1\right)x^{2-1}$$

Tango 1 mai i 3.

$$-x^{0}+3x^{2}+2\left(-1\right)x^{2-1}$$

Whakareatia 3 ki te 1.

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

Tango 1 mai i 2.

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

Mō tētahi kupu t, t^{1}=t.

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

Mō tētahi kupu t mahue te 0, t^{0}=1.

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

Aromātai

$$x^{3}-x^{2}-x+7$$

Ngā Upane Otinga

Pahekotia te -2x me x, ka -x.

$$7-x+x^{3}-x^{2}$$
