(3x-1)(x-1)=(4x+1)(x-1)的解为______.
详细过程
(3x-1)(x-1)=(4x+1)(x-1)
(3x-1)(x-1)-(4x+1)(x-1)=0
(x-1)(3x-1-4x-1)=0
-(x+2)(x-1)=0
x₁=-2
x₂=1
(3x-1)(x-1)=(4x+1)(x-1)
(3x-1)(x-1)-(4x+1)(x-1)=0
(x-1)[(3x-1)-(4x+1)]=0
(x-1)(3x-1-4x-1)=0
(x-1)(-x-2)=0
x-1=0或-x-2=0
解得x=1或x=-2
答:(3x-1)(x-1)=(4x+1)(x-1)的解为(x=1或x=-2)
解:3x²-x-3x+1=4x²+x-4x-1
x²-x-2=0
(x-2)(x+1)=0
x₁=2; x₂=-1
