7x^3-9x^2+13x-6 eching

$$7 x ^ { 3 } - 9 x ^ { 2 } + 13 x - 6$$

x ga nisbatan hosilani topish

$$21x^{2}-18x+13$$

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}.

$$3\times 7x^{3-1}+2\left(-9\right)x^{2-1}+13x^{1-1}$$

3 ni 7 marotabaga ko'paytirish.

$$21x^{3-1}+2\left(-9\right)x^{2-1}+13x^{1-1}$$

3 dan 1 ni ayirish.

$$21x^{2}+2\left(-9\right)x^{2-1}+13x^{1-1}$$

2 ni -9 marotabaga ko'paytirish.

$$21x^{2}-18x^{2-1}+13x^{1-1}$$

2 dan 1 ni ayirish.

$$21x^{2}-18x^{1}+13x^{1-1}$$

1 dan 1 ni ayirish.

$$21x^{2}-18x^{1}+13x^{0}$$

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

$$21x^{2}-18x+13x^{0}$$

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

$$21x^{2}-18x+13\times 1$$

Har qanday t sharti uchun t\times 1=t va 1t=t.

$$21x^{2}-18x+13$$

Baholash

$$7x^{3}-9x^{2}+13x-6$$
