急！！分解因式！！在线等！！

分解因式：
m^2-4n^2+4n-1
要有详细过程

Answer 1

解：原式=m^2-(4n^2-4n+1)
=m^2-(2n-1)^2
=(m+2n-1)(m-2n+1)
祝愉快O(∩_∩)O~

Answer 2

m²-4n²+4n-1
=m²-(4n²-4n+1)
=m²-(2n-1)²
=(m-2n+1)(m+2n-1)

Answer 3

你好！
m²-(4n²-4n+1)
=m²-(2n-1)²
=(m-2n+1)(m+2n-1)

Answer 4

m^2-4n^2+4n-1
=(m-2n)^2-1
=(m-2n+1)(m-2n+1)

Answer 5

m^2-4n^2+4n-1
=m^2-(2n-1)^2
=(m+2n-1)(m-2n+1)

Answer 6

分组分解法 原式=m^2-（4n^2-4n+1）=m^2-（2n-1）^2=(m+2n-1)(m-2n+1)
