y^2-3y+18=(y-6)(y-4) eching

$$y ^ { 2 } - 3 y + 18 = ( y - 6 ) ( y - 4 )$$

y uchun yechish

$$y=\frac{6}{7}\approx 0,857142857$$

Chiziqli tenglamalarni yechish bo'yicha qadamlar

y-6 ga y-4 ni ko‘paytirish orqali distributiv xususiyatdan foydalaning va ifoda sifatida birlashtiring.

$$y^{2}-3y+18=y^{2}-10y+24$$

Ikkala tarafdan y^{2} ni ayirish.

$$y^{2}-3y+18-y^{2}=-10y+24$$

0 ni olish uchun y^{2} va -y^{2} ni birlashtirish.

$$-3y+18=-10y+24$$

10y ni ikki tarafga qo’shing.

$$-3y+18+10y=24$$

7y ni olish uchun -3y va 10y ni birlashtirish.

$$7y+18=24$$

Ikkala tarafdan 18 ni ayirish.

$$7y=24-18$$

6 olish uchun 24 dan 18 ni ayirish.

$$7y=6$$

Ikki tarafini 7 ga bo‘ling.

$$y=\frac{6}{7}$$
