y=5(-2)^3-4(-2)^2+3(-2)-2 eching

$$y = 5 ( - 2 ) ^ { 3 } - 4 ( - 2 ) ^ { 2 } + 3 ( - 2 ) - 2$$

y uchun yechish

$$y=-64$$

Chiziqli tenglamalarni yechish bo'yicha qadamlar

3 daraja ko‘rsatkichini -2 ga hisoblang va -8 ni qiymatni oling.

$$y=5\left(-8\right)-4\left(-2\right)^{2}+3\left(-2\right)-2$$

-40 hosil qilish uchun 5 va -8 ni ko'paytirish.

$$y=-40-4\left(-2\right)^{2}+3\left(-2\right)-2$$

2 daraja ko‘rsatkichini -2 ga hisoblang va 4 ni qiymatni oling.

$$y=-40-4\times 4+3\left(-2\right)-2$$

16 hosil qilish uchun 4 va 4 ni ko'paytirish.

$$y=-40-16+3\left(-2\right)-2$$

-56 olish uchun -40 dan 16 ni ayirish.

$$y=-56+3\left(-2\right)-2$$

-6 hosil qilish uchun 3 va -2 ni ko'paytirish.

$$y=-56-6-2$$

-62 olish uchun -56 dan 6 ni ayirish.

$$y=-62-2$$

-64 olish uchun -62 dan 2 ni ayirish.

$$y=-64$$

y'ni tayinlash

$$y≔-64$$
