Whakaoti i te (2x^3-7x^2-3x+2)+(x-4)

$$( 2 x ^ { 3 } - 7 x ^ { 2 } - 3 x + 2 ) + ( x - 4 )$$

Aromātai

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

Ngā Upane Otinga

Pahekotia te -3x me x, ka -2x.

$$2x^{3}-7x^{2}-2x+2-4$$

Tangohia te 4 i te 2, ka -2.

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

Kimi Pārōnaki e ai ki x

$$6x^{2}-14x-2$$

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

Pahekotia te -3x me x, ka -2x.

$$\frac{\mathrm{d}}{\mathrm{d}x}(2x^{3}-7x^{2}-2x+2-4)$$

Tangohia te 4 i te 2, ka -2.

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

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}.

$$3\times 2x^{3-1}+2\left(-7\right)x^{2-1}-2x^{1-1}$$

Whakareatia 3 ki te 2.

$$6x^{3-1}+2\left(-7\right)x^{2-1}-2x^{1-1}$$

Tango 1 mai i 3.

$$6x^{2}+2\left(-7\right)x^{2-1}-2x^{1-1}$$

Whakareatia 2 ki te -7.

$$6x^{2}-14x^{2-1}-2x^{1-1}$$

Tango 1 mai i 2.

$$6x^{2}-14x^{1}-2x^{1-1}$$

Tango 1 mai i 1.

$$6x^{2}-14x^{1}-2x^{0}$$

Mō tētahi kupu t, t^{1}=t.

$$6x^{2}-14x-2x^{0}$$

Mō tētahi kupu t mahue te 0, t^{0}=1.

$$6x^{2}-14x-2$$
