3(x-2)-x(x-2)=0和(x-1)6^2=3(x-1)3(x-2)-x(x-2)=0和(x-1)6^2=3(x-1)3(x-2)-x(x-2)=0和(x-1)6^2=3(x-1)3(x-2)-

3(x-2)-x(x-2)=0和(x-1)6^2=3(x-1)
3(x-2)-x(x-2)=0和(x-1)6^2=3(x-1)

3(x-2)-x(x-2)=0和(x-1)6^2=3(x-1)
3(x-2)-x(x-2)=0
(3-x)(x-2)=0
所以3-x=0,或x-2=0
所以x=3,或x=2
(x-1)^2=3(x-1)
(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
所以x=1,或x=4
