x-78=5\left(y^{2}-14y+49\right)

\left(a-b\right)^{2}=a^{2}-2ab+b^{2} binom teoremasini \left(y-7\right)^{2} kengaytirilishi uchun ishlating.

x-78=5y^{2}-70y+245

5 ga y^{2}-14y+49 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.

x=5y^{2}-70y+245+78

78 ni ikki tarafga qo’shing.

x=5y^{2}-70y+323

323 olish uchun 245 va 78'ni qo'shing.
