Whakaoti i te (-2x)(-15x)(-7)=

$$(-2x)(-15x)(-7)=$$

Aromātai

$$-210x^{2}$$

Ngā Upane Otinga

Whakareatia te x ki te x, ka x^{2}.

$$-2x^{2}\left(-15\right)\left(-7\right)$$

Whakareatia te -2 ki te -15, ka 30.

$$30x^{2}\left(-7\right)$$

Whakareatia te 30 ki te -7, ka -210.

$$-210x^{2}$$

Kimi Pārōnaki e ai ki x

$$-420x$$

Ngā Upane e Whakamahi ana i te Tautuhinga o te Pārōnaki

Whakareatia te x ki te x, ka x^{2}.

$$\frac{\mathrm{d}}{\mathrm{d}x}(-2x^{2}\left(-15\right)\left(-7\right))$$

Whakareatia te -2 ki te -15, ka 30.

$$\frac{\mathrm{d}}{\mathrm{d}x}(30x^{2}\left(-7\right))$$

Whakareatia te 30 ki te -7, ka -210.

$$\frac{\mathrm{d}}{\mathrm{d}x}(-210x^{2})$$

Ko te pārōnaki o ax^{n} ko nax^{n-1}.

$$2\left(-210\right)x^{2-1}$$

Whakareatia 2 ki te -210.

$$-420x^{2-1}$$

Tango 1 mai i 2.

$$-420x^{1}$$

Mō tētahi kupu t, t^{1}=t.
