b^6-9(c-2)^2 eching

$$b ^ { 6 } - 9 ( c - 2 ) ^ { 2 }$$

Baholash

$$b^{6}-\left(3c-6\right)^{2}$$

Yechim qadamlari

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

$$b^{6}-9\left(c^{2}-4c+4\right)$$

-9 ga c^{2}-4c+4 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.

$$b^{6}-9c^{2}+36c-36$$

Kengaytirish

$$b^{6}-9c^{2}+36c-36$$
