分式,(x-2分之x-x+2分之x﹚÷x-2分之4x= ( x x ) 4x(_____ -_______ )÷ _____ =( x-2 x+2 ) x-2
分式,(x-2分之x-x+2分之x﹚÷x-2分之4x=
( x x ) 4x
(_____ -_______ )÷ _____ =
( x-2 x+2 ) x-2

分式,(x-2分之x-x+2分之x﹚÷x-2分之4x= ( x x ) 4x(_____ -_______ )÷ _____ =( x-2 x+2 ) x-2
(x-2分之x-x+2分之x﹚÷x-2分之4x
=[x(x+2)-x(x-2)]/(x+2)(x-2) * (x-2)/4x
=4x/(x+2)*1/4x
=1/(x+2)
