Solution

The given inequality is,

x+2-xx<2x+2-xx-2<0x+2-x-2xx<0x+2-3xx<0Now imposing condition on x+2, Case 1-When x+2>0....(1)then, x+2 =x+2, putting this we get, x+2-3xx<0-2x+2x<0x-1x>0So the interval will be, x(-,0)(1 ,)....(2)Now intersection of interval in equation (1) and (2) we get, x(-2,0)(1 ,)..........(3)Case 2-When x+2<0 or x(-,-2) ....(4)then, x+2 =-x-2, putting this we get, -x-2-3xx<0-4x-2x<02x-1x>0So the interval will be, x(-,0)(12 ,)....(5)Now intersection of interval in equation (4) and (5) we get, x(-,-2)..........(6)Now final interval will be the union of equation(3) and (6), so final answer,x(-,-2)(-2,0)(1 ,) (Answer)
