Datrys 9x^2-6x^3-2x^2+16x+8

$$9 x ^ { 2 } - 6 x ^ { 3 } - 2 x ^ { 2 } + 16 x + 8$$

Gwahaniaethu w.r.t. x

$$16+14x-18x^{2}$$

Camau gan Ddefnyddio Rheol Deilliadol ar gyfer Swm

Cyfuno 9x^{2} a -2x^{2} i gael 7x^{2}.

$$\frac{\mathrm{d}}{\mathrm{d}x}(7x^{2}-6x^{3}+16x+8)$$

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

$$2\times 7x^{2-1}+3\left(-6\right)x^{3-1}+16x^{1-1}$$

Lluoswch 2 â 7.

$$14x^{2-1}+3\left(-6\right)x^{3-1}+16x^{1-1}$$

Tynnu 1 o 2.

$$14x^{1}+3\left(-6\right)x^{3-1}+16x^{1-1}$$

Lluoswch 3 â -6.

$$14x^{1}-18x^{3-1}+16x^{1-1}$$

Tynnu 1 o 3.

$$14x^{1}-18x^{2}+16x^{1-1}$$

Tynnu 1 o 1.

$$14x^{1}-18x^{2}+16x^{0}$$

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

$$14x-18x^{2}+16x^{0}$$

Ar gyfer unrhyw derm t ac eithrio 0, t^{0}=1.

$$14x-18x^{2}+16\times 1$$

Ar gyfer unrhyw derm t, t\times 1=t a 1t=t.

$$14x-18x^{2}+16$$

Enrhifo

$$8+16x+7x^{2}-6x^{3}$$
