Céimeanna gearra réitigh

Chun cothromóidí a shuimiú nó a dhealú, fairsingigh iad chun a n-ainmneoirí a mheaitseáil. Méadaigh 12x^{2} faoi \frac{x-2}{x-2}.

$$\frac{12x^{2}\left(x-2\right)}{x-2}-\frac{1}{x-2}$$

Tá an t-ainmneoir céanna ag \frac{12x^{2}\left(x-2\right)}{x-2} agus \frac{1}{x-2} agus, mar sin, is féidir iad a dhealú trína n-uimhreoirí a dhealú.

$$\frac{12x^{2}\left(x-2\right)-1}{x-2}$$

Déan iolrúcháin in 12x^{2}\left(x-2\right)-1.

$$\frac{12x^{3}-24x^{2}-1}{x-2}$$

Céimeanna ag Baint Úsáid as Riail na nDíorthach don Líon

Chun cothromóidí a shuimiú nó a dhealú, fairsingigh iad chun a n-ainmneoirí a mheaitseáil. Méadaigh 12x^{2} faoi \frac{x-2}{x-2}.

$$\frac{\mathrm{d}}{\mathrm{d}x}(\frac{12x^{2}\left(x-2\right)}{x-2}-\frac{1}{x-2})$$

Tá an t-ainmneoir céanna ag \frac{12x^{2}\left(x-2\right)}{x-2} agus \frac{1}{x-2} agus, mar sin, is féidir iad a dhealú trína n-uimhreoirí a dhealú.

$$\frac{\mathrm{d}}{\mathrm{d}x}(\frac{12x^{2}\left(x-2\right)-1}{x-2})$$

Déan iolrúcháin in 12x^{2}\left(x-2\right)-1.

Do dhá fheidhm indifreáilte ar bith, is ionann díorthach líon an dá fheidhme agus an t-ainmneoir méadaithe faoi dhíorthach an uimhreora lúide an t-uimhreoir méadaithe faoi dhíorthach an ainmneora, agus iad ar fad roinnte faoin ainmneoir cearnaithe.

$$\frac{\left(x^{1}-2\right)\frac{\mathrm{d}}{\mathrm{d}x}(12x^{3}-24x^{2}-1)-\left(12x^{3}-24x^{2}-1\right)\frac{\mathrm{d}}{\mathrm{d}x}(x^{1}-2)}{\left(x^{1}-2\right)^{2}}$$

Is ionann díorthach iltéarmaigh agus suim dhíorthaigh a théarmaí. Is ionann díorthach téarma thairisigh agus 0. Is ionann díorthach ax^{n} agus nax^{n-1}.

Simpligh.

$$\frac{\left(x^{1}-2\right)\left(36x^{2}-48x^{1}\right)-\left(12x^{3}-24x^{2}-1\right)x^{0}}{\left(x^{1}-2\right)^{2}}$$

Méadaigh x^{1}-2 faoi 36x^{2}-48x^{1}.

$$\frac{x^{1}\times 36x^{2}+x^{1}\left(-48\right)x^{1}-2\times 36x^{2}-2\left(-48\right)x^{1}-\left(12x^{3}-24x^{2}-1\right)x^{0}}{\left(x^{1}-2\right)^{2}}$$

Méadaigh 12x^{3}-24x^{2}-1 faoi x^{0}.

$$\frac{x^{1}\times 36x^{2}+x^{1}\left(-48\right)x^{1}-2\times 36x^{2}-2\left(-48\right)x^{1}-\left(12x^{3}x^{0}-24x^{2}x^{0}-x^{0}\right)}{\left(x^{1}-2\right)^{2}}$$

Chun cumhachtaí an bhoinn chéanna a mhéadú, suimigh a n-easpónaint.
