-d^3+10d^2-28d+84 eching

$$- d ^ { 3 } + 10 d ^ { 2 } - 28 d + 84$$

d ga nisbatan hosilani topish

$$\left(2-d\right)\left(3d-14\right)$$

Yig'indi uchun derivativ qoidasidan foydalanish qadamlari

Polinomialning hosilasi bu uning shartlari hosilasining yig‘indisiga teng. Konstant shartning hosilasi 0. ax^{n} ning hosilasi nax^{n-1}.

$$3\left(-1\right)d^{3-1}+2\times 10d^{2-1}-28d^{1-1}$$

3 ni -1 marotabaga ko'paytirish.

$$-3d^{3-1}+2\times 10d^{2-1}-28d^{1-1}$$

3 dan 1 ni ayirish.

$$-3d^{2}+2\times 10d^{2-1}-28d^{1-1}$$

2 ni 10 marotabaga ko'paytirish.

$$-3d^{2}+20d^{2-1}-28d^{1-1}$$

2 dan 1 ni ayirish.

$$-3d^{2}+20d^{1}-28d^{1-1}$$

1 dan 1 ni ayirish.

$$-3d^{2}+20d^{1}-28d^{0}$$

Har qanday t sharti uchun t^{1}=t.

$$-3d^{2}+20d-28d^{0}$$

Har qanday t sharti uchun (0 bundan mustasno) t^{0}=1.

$$-3d^{2}+20d-28$$

Baholash

$$84-28d+10d^{2}-d^{3}$$
