4x^2+x+1 eching

$$4 { x }^{ 2 } +x+1$$

x ga nisbatan hosilani topish

$$8x+1$$

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}.

$$2\times 4x^{2-1}+x^{1-1}$$

2 ni 4 marotabaga ko'paytirish.

$$8x^{2-1}+x^{1-1}$$

2 dan 1 ni ayirish.

$$8x^{1}+x^{1-1}$$

1 dan 1 ni ayirish.

$$8x^{1}+x^{0}$$

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

$$8x+x^{0}$$

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

$$8x+1$$

Baholash

$$4x^{2}+x+1$$
