1. Solve the inequality
Solution:
There are two cases for this problem:
First, if x-2>0=>x>2, then,2x+5<0=>x<-5/2, then, in this case, no solution
Second, if x-2<0=>x<2, then,2x+5>0=>x>-5/2, then, in this case, the solution is -5/2<x<2

State the interval(s) where the inequality is valid using the symbols <, >.
