解方程2(x-1)²=4x-4
解方程2(x-1)²=4x-4
2(x-1)²=4x-4
2(x-1)²=4(x-1)
2(x-1)²-4(x-1)=0
2(x-1)[(x-1)-2]=0
2(x-1)(x-3)=0
x1=1,x2=3

2(x-1)²=4x-4
2(x-1)²-4(x-1)=0
2(x-1)(x-1-2)=0
x1=1 x2=3
不懂可追问,有帮助请采纳,谢谢!
两边除以2
(x-1)²=2x-2=2(x-1)
(x-1)²-2(x-1)=0
(x-1)(x-1-2)=0
(x-1)(x-3)=0
x=1,x=3
2(x-1)²=4x-4
(x-1)²=2(x-1)
(x-1)²-2(x-1)=0
(x-1)(x-3)=0
x=1
x=3
