/x-1/+/x^2-3/>2解不等式,我绝对值不等式忘记了
斜杠为绝对值

/x-1/+/x^2-3/>2解不等式,我绝对值不等式忘记了斜杠为绝对值

|x-1|+|x^2-3|>2

(1)当x<-√3时,x-1<0,x^2-3>0,

    不等式化为  -(x-1)+(x^2-3)>2

                  x^2-x-4<0

                 (1-√17)/2<x<(1+√17)/2                  

        综合前提条件,-√3>(1-√17)/2  ,所以x无解;

(2)-√3≤x<1时,x-1<0,x^2-3≤0,

    不等式化为  -(x-1)-(x^2-3)>2

                  x^2+x-2<0

                 (x+2)(x-1)<0

                          -2<x<1

        综合前提条件,不等式的解为-√3≤x<1;

(3)1≤x<√3时,x-1≥0,x^2-3<0,

    不等式化为  (x-1)-(x^2-3)>2

                  x^2-x<0

                  x(x-1)<0

                          0<x<1

        综合前提条件,不等式无解;

(4)x≥√3时,x-1>0,x^2-3≥0,

    不等式化为  (x-1)+(x^2-3)>2

                  x^2+x-6>0

               (x+3)(x-2)>-0

            x>2   或  x<-3

        综合前提条件,不等式的解为x>2

综上,不等式的解为-√3≤x<1

                         或x>2

/x-1/+/x^-3/>2
1-x+3-x^>2
x+x^>-1
x>0
