x²+12xy+36y²
=(x+6y)^2
4分之1m²+3mn+9n²
=(m/2+3n)^2
a²-2a(b+c)+(b+c)²
=(a-b-c)^2
4x³-4x²+x
=x(4x^2-4x+1)
=x(2x-1)^2
4a²-12ab+9b²
=(2a-3b)^2
a²b²+8abc+16c²
=(ab+c)^2

很高兴回答你的问题
①x²+12xy+36y²
(x+6y)^2
②1/4m²+3mn+9n²
(1/2m+3n)^2
③a²-2a(b+c)+(b+c)²
[a-(b+c)]^2
④4x³-4x²+x
=x(4x^2-4x+1)
=x(2x-1)^2
⑤4a²-12ab+9b²
(2a-3b)^2
⑥a²b²+8abc+16c²
(ab+4c)^2
