[x+1 / x-1] > 0
This will satisfy in two cases:
Case:1
x+1>0 and x-1>0
x > -1 and x > 1
the common region is x>1
Case:2
x+1<0 and x-1<0
x < -1 and x < 1
the common region is x < -1
So the region is x belongs to (-∞,-1) and (1,∞)
This will satisfy in two cases:
Case:1
x+1>0 and x-1>0
x > -1 and x > 1
the common region is x>1
Case:2
x+1<0 and x-1<0
x < -1 and x < 1
the common region is x < -1
So the region is x belongs to (-∞,-1) and (1,∞)
