< X < 6时,化简|x-2|-|x-6|=_______.如题【非诚勿扰】
∵2<X<6
∴原式=(x-2)-(6-x)
=x-2-6+x
=2x-8
原式=x-2-(6-x)=2x-8
解
原式=(x-2)-(6-x)=2x-8
原式=(X-2)-(6-X)=X-2-6+X=2X-8
已知x<-2,化简|-x|+|x+2|-|2-x|
简化代数式(x²-1)/(x²+2x)×x/(x-1),并判断当x满足不等式组x+2-6时该代数式的符号x2-1 x2+2x ÷x-1 x =x2-1 x2+2x •x x-1 =(x -1)(x+1) x(x +2) •x x-1 =x+1 x+2 x+2<1① 2(x-1)>-6② 解不等式①,得x<-1
计算题:① <(x-1/x+1)-(x+1/x-1)>÷x+3/x*x+4x+4)② (a*a-2ab+b*b)/(a*a+ab)*(a+b)/(ab-b*b)③ (2x/x*x-1)-1/(x-1)④ -a-6约分:① 1/2*x*x*y ,1/3*x*y*y② 1/(2x+2) ,3/(x*x-1)化简:① (3+x)/(2+x)+(x*x-4)
若1<x<2,化简|x-2| /x-2-|x-1|/1-x+|x|/x的结果为
3<x<10 时,化简|10-x|-|4-2x|+3x
