(x-1)²=3(1-x)用分解因式法来解

(x-1)²=3(1-x)用分解因式法来解
(x-1)²=3(1-x)用分解因式法来解

(x-1)²=3(1-x)用分解因式法来解
(x-1)²+3(x-1)=0
(x-1)(x-1+3)=0
(x-1)(x+2)=0
∴x=1 x=-2

(x-1)²=3(1-x)
(x-1)²-3(x-1)=0
(x-1)(x-1-3)=0
(x-1)(x-4)=0
所以X-1=0或X-4=0
X1=1，X2=4你这个(x-1)²-3(x-1)=0有点问题

详细说的话(x-1)²=3(1-x)
﹙x-1﹚...

全部展开

(x-1)²=3(1-x)
(x-1)²-3(x-1)=0
(x-1)(x-1-3)=0
(x-1)(x-4)=0
所以X-1=0或X-4=0
X1=1，X2=4
