因式分解(xy-x2)3-x3(y-x)因式分解(xy-x2)3-x3(y-x)因式分解(xy-x2)3-x3(y-x)原题是否是这样的:(xy-x^2)^3-x^3(y-x)=x^3(y-x)^3-

因式分解(xy-x2)3-x3(y-x)
因式分解(xy-x2)3-x3(y-x)

因式分解(xy-x2)3-x3(y-x)
原题是否是这样的:
(xy-x^2)^3-x^3(y-x)
=x^3(y-x)^3-x^3(y-x)
=x^3(y-x)〔(y-x)^2-1〕
=x^3(y-x)(y-x+1)(y-x-1)

(xy-x2)3-x3(y-x)
=x(y-x)-x^3(y-x)
=x(y-x)(1-x^2)
=x(y-x)(1-x)(1+x)免费数学资源学习习题下载math.jxt123.网com
