$1)\; \; (9a^2+6ab+b^2)-6ax-2bx=(3a+b)^2-2x(3a+b)=\\\\=(3a+b)(3a+b-2x)\\\\\\2)\; \; (4m^2+n^2+4mn)+(4m+2n)+1=\underbrace {(2m+n)^2+2\cdot (2m+n)+1}_{a^2+2a+1=(a+1)^2}=\\\\=\Big((2m+n)+1\Big)^2=(2m+n+1)^2$

Ответ:

Объяснение:

(a+b)²=a²+2ab+b²

b) 9a²+6ab+b²-6ax-2bx=(3a)²+3·3a·b+b²-6ax-2bx

=(3a+b)²-2x(3a+b)=(3a+b)((3a+b)-2x)=(3a+b)(3a+b-2x)

c) 4m²+n²+4mn+4m+2n+1=(2m)²+2·2m·n+n²+2(2m+n)·1+1²=

=(2m+n)²+2(2m+n)·1+1²=(2m+n+1)²
