x^2+ax-1 eching

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

x ga nisbatan hosilani topish

$$2x+a$$

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}.

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

2 dan 1 ni ayirish.

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

1 dan 1 ni ayirish.

$$2x^{1}+ax^{0}$$

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

$$2x+ax^{0}$$

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

$$2x+a\times 1$$

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

$$2x+a$$

Baholash
