(x-1)^3(x+1)(x-2)/(x+4)
(x+1)(x+2)(x+3)(x+4)+1
化简{x²-2x分之x+2-x²-4x+4x分之x-1}除以X分之(x-1)(X-4)乘以(2-x)
(x+2/x+1)-(x+4/x+3)-(x+3/x+2)+(x+5/x+4)
[(x+2)/(x²+2x)-(x-1)/(x²-4x+4)]÷(x-4)/x
计算(x*x+4x+5)/(x+2)-(x*x+6x+10)/(x+3)+1
(1) x-3/x-2 - x-5/x-4=x-7/x-6 - x-9/x-8
解方程:(x-8)/(x-3)-(x-9)/(x-4)=(x+7)/(x+8)-(x+2)/(x+3)
(x+2/x平方-2x - x-1/x平方-4x+4)÷(x平方-16/x平方+4x)
(x-2)/(x+2)-16/(x^2-4)=(x+2)/(x-2)
先化简(x平方-4x+4)/(x平方-2x)÷(x-4/x)
