(2a+175)2=75 eching

$$( 2 a + 175 ) 2 = 75$$

a uchun yechish

$$a = -\frac{275}{4} = -68\frac{3}{4} = -68,75$$

Chiziqli tenglamalarni yechish bo'yicha qadamlar

Ikki tarafini 2 ga bo‘ling.

$$2a+175=\frac{75}{2}$$

Ikkala tarafdan 175 ni ayirish.

$$2a=\frac{75}{2}-175$$

175 ni \frac{350}{2} kasrga o‘giring.

$$2a=\frac{75}{2}-\frac{350}{2}$$

\frac{75}{2} va \frac{350}{2} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$2a=\frac{75-350}{2}$$

-275 olish uchun 75 dan 350 ni ayirish.

$$2a=-\frac{275}{2}$$

Ikki tarafini 2 ga bo‘ling.

$$a=\frac{-\frac{275}{2}}{2}$$

\frac{-\frac{275}{2}}{2} ni yagona kasrga aylantiring.

$$a=\frac{-275}{2\times 2}$$

4 hosil qilish uchun 2 va 2 ni ko'paytirish.

$$a=\frac{-275}{4}$$

\frac{-275}{4} kasri manfiy belgini olib tashlash bilan -\frac{275}{4} sifatida qayta yozilishi mumkin.

$$a=-\frac{275}{4}$$
