Ar gyfer unrhyw ddau ffwythiant y mae modd eu gwahaniaethu, deilliad cyniferydd dau ffwythiant yw’r enwadur wedi’i luosi â deilliad yr enwadur wedi’i dynnu o’r rhifiadur wedi’i luosi â deilliad yr enwadur, y cwbl wedi’i rannu â’r enwadur wedi'i sgwario.

$$\frac{\left(-3t^{2}+2t^{1}+7\right)\frac{\mathrm{d}}{\mathrm{d}t}(2t^{3})-2t^{3}\frac{\mathrm{d}}{\mathrm{d}t}(-3t^{2}+2t^{1}+7)}{\left(-3t^{2}+2t^{1}+7\right)^{2}}$$

Deilliad polynomaial yw swm deilliadau ei dermau. Deilliad term cyson yw 0. Y deilliad o ax^{n} yw nax^{n-1}.

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

Symleiddio.

$$\frac{\left(-3t^{2}+2t^{1}+7\right)\times 6t^{2}-2t^{3}\left(-6t^{1}+2t^{0}\right)}{\left(-3t^{2}+2t^{1}+7\right)^{2}}$$

Lluoswch -3t^{2}+2t^{1}+7 â 6t^{2}.

$$\frac{-3t^{2}\times 6t^{2}+2t^{1}\times 6t^{2}+7\times 6t^{2}-2t^{3}\left(-6t^{1}+2t^{0}\right)}{\left(-3t^{2}+2t^{1}+7\right)^{2}}$$

Lluoswch 2t^{3} â -6t^{1}+2t^{0}.

$$\frac{-3t^{2}\times 6t^{2}+2t^{1}\times 6t^{2}+7\times 6t^{2}-\left(2t^{3}\left(-6\right)t^{1}+2t^{3}\times 2t^{0}\right)}{\left(-3t^{2}+2t^{1}+7\right)^{2}}$$

Cyfuno termau sydd yr un peth.

$$\frac{-6t^{4}+8t^{3}+42t^{2}}{\left(-3t^{2}+2t^{1}+7\right)^{2}}$$

Ar gyfer unrhyw derm t, t^{1}=t.

$$\frac{-6t^{4}+8t^{3}+42t^{2}}{\left(-3t^{2}+2t+7\right)^{2}}$$
