61y^2-4y+4 eching

$$61 y ^ { 2 } - 4 y + 4$$

y ga nisbatan hosilani topish

$$122y-4$$

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}.

$$2\times 61y^{2-1}-4y^{1-1}$$

2 ni 61 marotabaga ko'paytirish.

$$122y^{2-1}-4y^{1-1}$$

2 dan 1 ni ayirish.

$$122y^{1}-4y^{1-1}$$

1 dan 1 ni ayirish.

$$122y^{1}-4y^{0}$$

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

$$122y-4y^{0}$$

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

$$122y-4$$

Baholash
