|X-2 | - | x + 1 | > A is constant on X ∈ R, and the value range of a is obtained
|X-2 | - | x + 1 | > a holds
And | X-2 | - | x + 1 | denotes the distance from the corresponding point of X on the number axis to the corresponding point of 2 minus the distance from it to the corresponding point of - 1, and its minimum value is - 3,
So there is a
