We can identify critical points: x=-2, -1, 3.
We need to evaluate the expression for x<-2, -2<x<-1, -1<x<3, x>3.
When x<-2 the sign of each factor is (-)(-)(-)<0. So x<-2 is one solution.
When -2<x<-1 we have (-)(+)(-)>0.
When -1<x<3, we have (+)(+)(-)<0. So -1<x<3 is a solution.
When x>3, we have (+)(+)(+)>0.
SOLUTION: x<-2 or -1<x<3.
