(2x²-x)²-4(2x²-x)+3=0
(2x²-x-1)(2x²-x-3)=0
(2x+1)(x-1)(2x-3)(x+1)=0
x1=-1/2
x2=1
x3=3/2
x4=-1
2x-根号（2x-1）-3=0
这题题目是否有问题?根号2x-1是一体的(2x²-x)²-4(2x²-x)+3=0(2x²-x-1)(2x²-x-3)=0(2x+1)(x-1)(2x-3)(x+1)=0x1=-1/2x2=1x3=3/2x4=-12x-根号（2x-1）-3=02x-1-根号（2x-1）-2=0(根号（2x-1）-2) (根号（2x-1）+1)=0根号（2x-1）=2或根号（2x-1）=-1（舍去）所以根号（2x-1）=2解得2x-1=4x=5/2祝学习进步
