d/dxleft(9x^2-18xright) eching

$$\frac{d}{d x } \left(9 { x }^{ 2 } -18x \right)$$

Baholash

$$18\left(x-1\right)$$

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}.

$$2\times 9x^{2-1}-18x^{1-1}$$

2 ni 9 marotabaga ko'paytirish.

$$18x^{2-1}-18x^{1-1}$$

2 dan 1 ni ayirish.

$$18x^{1}-18x^{1-1}$$

1 dan 1 ni ayirish.

$$18x^{1}-18x^{0}$$

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

$$18x-18x^{0}$$

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

$$18x-18$$

x ga nisbatan hosilani topish

$$18$$
