若分式x²/（x²+x）化简为x/（1+x）,则x满足的条件是_____________Ax≠-1或x≠0Bx≠-1Cx≠-1且x≠0DX≠0若分式x²/（x²

若分式x²/（x²+x）化简为x/（1+x）,则x满足的条件是_____________A x≠-1或x≠0 B x≠-1 C x≠-1且x≠0 D X≠0
若分式x²/（x²+x）化简为x/（1+x）,则x满足的条件是_____________
A x≠-1或x≠0 B x≠-1 C x≠-1且x≠0 D X≠0

若分式x²/（x²+x）化简为x/（1+x）,则x满足的条件是_____________A x≠-1或x≠0 B x≠-1 C x≠-1且x≠0 D X≠0
x^2/(x^2+x)
=x^2/[x(1+x)]
=x/(1+x)
只要分母有意义,就可以.
x(1+x) ≠0
x≠-1且x≠0
