若X2+1除以X=5,求X4+X2+1除以X4-X2+1若X2+1除以X=5,求X4+X2+1除以X4-X2+1若X2+1除以X=5,求X4+X2+1除以X4-X2+1等于12/11X2+1除以X=5

若X2+1除以X=5,求X4+X2+1除以X4-X2+1
若X2+1除以X=5,求X4+X2+1除以X4-X2+1

若X2+1除以X=5,求X4+X2+1除以X4-X2+1
等于12/11


X2+1除以X=5-----------(X4+X2+1)/X2=25--------------X4+X2+1=25*X2
----------------------------------------------------------------X4-X2+1=25*X2-4X2=21X2
X4+X2+1除以X4-X2+1=25X2除以21X2=25/21为什么(X4+X2...
