x^2(2x-y)-2x+y因式分解

x^2(2x-y)-2x+y因式分解
x^2(2x-y)-2x+y
原式=x^2(2x-y)-（2x-y）
=（2x-y）（x^2-1)
=(2x-y)(x+1)(x-1)

x^2(2x-y)-2x+y
=x^2(2x-y)-(2x-y)
= (2x-y)(x^2-1)
=(2x-y)(x+1)(x-1)

原式=x^2（2x-y)-(2x-y)=(x^2-1)(2x-y)=(x+1)( x-1 ) (2x-y)

x^2(2x-y)-2x+y
=x^2(2x-y)-(2x-y)
=(2x-y)(x^2-1)
=(2x-y)(x+1)(x-1)

x^2(2x-y)-2x+y
=x^2(2x-y)-(2x-y)
=(2x-y)(x+1)(x-1)
