F(x)=x^3-15x^2+160x-120 eching

$$F ( x ) = x ^ { 3 } - 15 x ^ { 2 } + 160 x - 120$$

x ga nisbatan hosilani topish

$$3x^{2}-30x+160$$

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}.

$$3x^{3-1}+2\left(-15\right)x^{2-1}+160x^{1-1}$$

3 dan 1 ni ayirish.

$$3x^{2}+2\left(-15\right)x^{2-1}+160x^{1-1}$$

2 ni -15 marotabaga ko'paytirish.

$$3x^{2}-30x^{2-1}+160x^{1-1}$$

2 dan 1 ni ayirish.

$$3x^{2}-30x^{1}+160x^{1-1}$$

1 dan 1 ni ayirish.

$$3x^{2}-30x^{1}+160x^{0}$$

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

$$3x^{2}-30x+160x^{0}$$

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

$$3x^{2}-30x+160\times 1$$

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

$$3x^{2}-30x+160$$

Baholash

$$x^{3}-15x^{2}+160x-120$$
