3x+2x^2+4= eching

$$3 x + 2 x ^ { 2 } + 4 =$$

x ga nisbatan hosilani topish

$$4x+3$$

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}.

$$3x^{1-1}+2\times 2x^{2-1}$$

1 dan 1 ni ayirish.

$$3x^{0}+2\times 2x^{2-1}$$

2 ni 2 marotabaga ko'paytirish.

$$3x^{0}+4x^{2-1}$$

2 dan 1 ni ayirish.

$$3x^{0}+4x^{1}$$

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

$$3x^{0}+4x$$

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

$$3\times 1+4x$$

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

$$3+4x$$

Baholash

$$2x^{2}+3x+4$$
