y=\left(x^{2}+14x+49\right)\left(x+3\right)+35
\left(a+b\right)^{2}=a^{2}+2ab+b^{2} binom teoremasini \left(x+7\right)^{2} kengaytirilishi uchun ishlating.
y=x^{3}+17x^{2}+91x+147+35
x^{2}+14x+49 ga x+3 ni ko‘paytirish orqali distributiv xususiyatdan foydalaning va ifoda sifatida birlashtiring.
y=x^{3}+17x^{2}+91x+182
182 olish uchun 147 va 35'ni qo'shing.
