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

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

Baholash

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

Yechim qadamlari

\left(a-b\right)^{2}=a^{2}-2ab+b^{2} binom teoremasini \left(-6-c\right)^{2} kengaytirilishi uchun ishlating.

$$36+12c+c^{2}-2b\left(-b-c\right)+b^{2}$$

-2b ga -b-c ni ko'paytirish orqali distributiv xususiyatdan foydalanish.

$$36+12c+c^{2}+2b^{2}+2bc+b^{2}$$

3b^{2} ni olish uchun 2b^{2} va b^{2} ni birlashtirish.

$$36+12c+c^{2}+3b^{2}+2bc$$

Kengaytirish

$$3b^{2}+2bc+c^{2}+12c+36$$
