Best ResponseYou've already chosen the best response.0\[\Hugex15\bigg2 > 0\] >x<4 So lets take x as 3. Substituting, Okay positive. x>2 So lets take x as 1. Substituting, Okay positive. x>8 So lets take x as 9. Substituting, Okay positive. x<6 So lets take x as 7. Substituting, Okay positive. So that means all the solutions are acceptable.

Best ResponseYou've already chosen the best response.1So, x<4, x<6 > x<6 x>2, x>8 > x>8 right? @wio

Best ResponseYou've already chosen the best response.1Looking at x<4 and x>2 is enough to tell you all solutions work.

Best ResponseYou've already chosen the best response.1Combining these equations: \[ 2<x<4\\ x<6, \quad x>8 \]Makes me thing it's \(x\in (\infty,6)\cup (2,4)\cup (8,\infty)\)

DLS

Best ResponseYou've already chosen the best response.0\[x\in (8,6)\cup (2,4)\cup (8,\infty)\] is the answer
