Whakaoti i te (7y^2+y-8)+(9y^2-y-5)

$$( 7 y ^ { 2 } + y - 8 ) + ( 9 y ^ { 2 } - y - 5 )$$

Aromātai

$$16y^{2}-13$$

Ngā Upane Otinga

Pahekotia te 7y^{2} me 9y^{2}, ka 16y^{2}.

$$16y^{2}+y-8-y-5$$

Pahekotia te y me -y, ka 0.

$$16y^{2}-8-5$$

Tangohia te 5 i te -8, ka -13.

$$16y^{2}-13$$

Kimi Pārōnaki e ai ki y

$$32y$$

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

Pahekotia te 7y^{2} me 9y^{2}, ka 16y^{2}.

$$\frac{\mathrm{d}}{\mathrm{d}y}(16y^{2}+y-8-y-5)$$

Pahekotia te y me -y, ka 0.

$$\frac{\mathrm{d}}{\mathrm{d}y}(16y^{2}-8-5)$$

Tangohia te 5 i te -8, ka -13.

$$\frac{\mathrm{d}}{\mathrm{d}y}(16y^{2}-13)$$

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}.

$$2\times 16y^{2-1}$$

Whakareatia 2 ki te 16.

$$32y^{2-1}$$

Tango 1 mai i 2.

$$32y^{1}$$

Mō tētahi kupu t, t^{1}=t.

$$32y$$
