a^3-4a^2+2a-1 eching

$$a ^ { 3 } - 4 a ^ { 2 } + 2 a - 1$$

a ga nisbatan hosilani topish

$$3a^{2}-8a+2$$

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}.

$$3a^{3-1}+2\left(-4\right)a^{2-1}+2a^{1-1}$$

3 dan 1 ni ayirish.

$$3a^{2}+2\left(-4\right)a^{2-1}+2a^{1-1}$$

2 ni -4 marotabaga ko'paytirish.

$$3a^{2}-8a^{2-1}+2a^{1-1}$$

2 dan 1 ni ayirish.

$$3a^{2}-8a^{1}+2a^{1-1}$$

1 dan 1 ni ayirish.

$$3a^{2}-8a^{1}+2a^{0}$$

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

$$3a^{2}-8a+2a^{0}$$

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

$$3a^{2}-8a+2\times 1$$

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

$$3a^{2}-8a+2$$

Baholash
