y=-1/3*(-1)^2+2(-1)+3 eching

$$y = - \frac { 1 } { 3 } \cdot ( - 1 ) ^ { 2 } + 2 ( - 1 ) + 3$$

y uchun yechish

$$y=\frac{2}{3}\approx 0,666666667$$

Chiziqli tenglamalarni yechish bo'yicha qadamlar

2 daraja ko‘rsatkichini -1 ga hisoblang va 1 ni qiymatni oling.

$$y=-\frac{1}{3}+2\left(-1\right)+3$$

-2 hosil qilish uchun 2 va -1 ni ko'paytirish.

$$y=-\frac{1}{3}-2+3$$

2 ni \frac{6}{3} kasrga o‘giring.

$$y=-\frac{1}{3}-\frac{6}{3}+3$$

-\frac{1}{3} va \frac{6}{3} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$y=\frac{-1-6}{3}+3$$

-7 olish uchun -1 dan 6 ni ayirish.

$$y=-\frac{7}{3}+3$$

3 ni \frac{9}{3} kasrga o‘giring.

$$y=-\frac{7}{3}+\frac{9}{3}$$

-\frac{7}{3} va \frac{9}{3} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$y=\frac{-7+9}{3}$$

2 olish uchun -7 va 9'ni qo'shing.

$$y=\frac{2}{3}$$

y'ni tayinlash

$$y≔\frac{2}{3}$$
