Yechim qadamlari

x^{2} hosil qilish uchun x va x ni ko'paytirish.

$$x^{2}-2x^{2}$$

-x^{2} ni olish uchun x^{2} va -2x^{2} ni birlashtirish.

$$-x^{2}$$

$$-2x$$

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}.

$$2x^{2-1}+\left(-2x\right)x^{1-1}$$

2 dan 1 ni ayirish.

$$2x^{1}+\left(-2x\right)x^{1-1}$$

1 dan 1 ni ayirish.

$$2x^{1}+\left(-2x\right)x^{0}$$

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

$$2x+\left(-2x\right)x^{0}$$

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

$$2x+\left(-2x\right)\times 1$$

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

$$2x-2x$$
