y=\left(x^{2}-6x+9\right)\left(x+3\right)-4
\left(a-b\right)^{2}=a^{2}-2ab+b^{2} binom teoremasini \left(x-3\right)^{2} kengaytirilishi uchun ishlating.
y=x^{3}-3x^{2}-9x+27-4
x^{2}-6x+9 ga x+3 ni ko‘paytirish orqali distributiv xususiyatdan foydalaning va ifoda sifatida birlashtiring.
y=x^{3}-3x^{2}-9x+23
23 olish uchun 27 dan 4 ni ayirish.
