计算(x*x+4x+5)/(x+2)-(x*x+6x+10)/(x+3)+1
计算:(x+2/x^2-2x-x-1/x^2-4x+4)×x/4-x
(x+2/x^2-2x-x-1/x^2-4x+4)/x-4/x因式分解
化简[(x+2)/(x²-2x)+(x-1)/(x²-4x+4)]除以(x-4)/x
[(x+2)/(x²+2x)-(x-1)/(x²-4x+4)]÷(x-4)/x
计算.(1+2/x-x+1/x-2)除以x+4/x平方-2x
计算.(1+2/x-x+1/x-2)除以x+4/x平方-2x
请问这道题咋做 :(x)X (x+1) X (x+2) X (x+3) =360
35道.符号^代表平方.读起来就是(X的平方).1,x^-x-202,x^-9x+203,x^-9x-204,x^+9x+205,x^-18x+326,x^+14x-317,x^+18x+328,x^+14x-329,x^+19x+4810,x^+47x-4811,x^+13x-4812,x^+2x-4813,x^+26x+4814,x^-22x-4815,x^+17x+7216,x^+21x-10017,x^-x-7218,x
先化简再求值先化简再求值:(x-x/x+1)(x+1/x^2+4x+4)(x^2-4/x^2-2x),其中x=-0.5
(X-3分之x-1-x分之x-4)除以x的平方+3x分之(x+3)(x-2),其中(x-1)(x-2)=0
(1)(2x/x-1)-(x-1/x)=1 (2)(x^2-4x/x^2-1)+1=2x/x+1 (3)(x+4/x^2+2x)-(1/x+2)=(2/x)+1
