Yechim qadamlari

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

$$\left(-m\right)^{2}-2\left(-m\right)n+n^{2}$$

2 daraja ko‘rsatkichini -m ga hisoblang va m^{2} ni qiymatni oling.

$$m^{2}-2\left(-m\right)n+n^{2}$$

2 hosil qilish uchun -2 va -1 ni ko'paytirish.

$$m^{2}+2mn+n^{2}$$

Kengaytirish
