Whakaoti i te f(x)=x^2/x^2-3x+70

$$f ( x ) = \frac { x ^ { 2 } } { x ^ { 2 } - 3 x + 70 }$$

Kimi Pārōnaki e ai ki x

$$\frac{x\left(140-3x\right)}{\left(x^{2}-3x+70\right)^{2}}$$

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

Mō ngā pānga e rua e taea ana te pārōnaki, ko te pārōnaki o te otinga o ngā pānga e rua ko te tauraro whakareatia ki te pārōnaki o te taurunga tango i te taurunga whakareatia ki te pārōnaki o te tauraro, ā, ka whakawehea te katoa ki te tauraro kua pūruatia.

$$\frac{\left(x^{2}-3x^{1}+70\right)\frac{\mathrm{d}}{\mathrm{d}x}(x^{2})-x^{2}\frac{\mathrm{d}}{\mathrm{d}x}(x^{2}-3x^{1}+70)}{\left(x^{2}-3x^{1}+70\right)^{2}}$$

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}.

$$\frac{\left(x^{2}-3x^{1}+70\right)\times 2x^{2-1}-x^{2}\left(2x^{2-1}-3x^{1-1}\right)}{\left(x^{2}-3x^{1}+70\right)^{2}}$$

Whakarūnātia.

$$\frac{\left(x^{2}-3x^{1}+70\right)\times 2x^{1}-x^{2}\left(2x^{1}-3x^{0}\right)}{\left(x^{2}-3x^{1}+70\right)^{2}}$$

Whakareatia x^{2}-3x^{1}+70 ki te 2x^{1}.

$$\frac{x^{2}\times 2x^{1}-3x^{1}\times 2x^{1}+70\times 2x^{1}-x^{2}\left(2x^{1}-3x^{0}\right)}{\left(x^{2}-3x^{1}+70\right)^{2}}$$

Whakareatia x^{2} ki te 2x^{1}-3x^{0}.

$$\frac{x^{2}\times 2x^{1}-3x^{1}\times 2x^{1}+70\times 2x^{1}-\left(x^{2}\times 2x^{1}+x^{2}\left(-3\right)x^{0}\right)}{\left(x^{2}-3x^{1}+70\right)^{2}}$$

Hei whakarea pū o te pūtake ōrite, tāpiri ana taupū.

$$\frac{2x^{2+1}-3\times 2x^{1+1}+70\times 2x^{1}-\left(2x^{2+1}-3x^{2}\right)}{\left(x^{2}-3x^{1}+70\right)^{2}}$$

Whakarūnātia.

$$\frac{2x^{3}-6x^{2}+140x^{1}-\left(2x^{3}-3x^{2}\right)}{\left(x^{2}-3x^{1}+70\right)^{2}}$$

Pahekotia ngā kīanga tau ōrite.

$$\frac{-3x^{2}+140x^{1}}{\left(x^{2}-3x^{1}+70\right)^{2}}$$

Mō tētahi kupu t, t^{1}=t.

$$\frac{-3x^{2}+140x}{\left(x^{2}-3x+70\right)^{2}}$$

Aromātai

$$\frac{x^{2}}{x^{2}-3x+70}$$
