8m的3次方-4m^+2m-1因式分解8m的3次方-4m^+2m-1因式分解8m的3次方-4m^+2m-1因式分解8m的3次方-4m^2+2m-1=4m^2(2m-1)+2m-1=(4m^2+1)(2

8m的3次方-4m^+2m-1因式分解
8m的3次方-4m^+2m-1因式分解

8m的3次方-4m^+2m-1因式分解
8m的3次方-4m^2+2m-1
=4m^2(2m-1)+2m-1
=(4m^2+1)(2m-1)

输入有误。。。。。。。。。。。

原式=4m²(2m-1)-(2m-1)
=(4m²-1)(2m-1)
=(2m+1)(2m-1)(2m-1)
=(2m+1)(2m-1)²
