===> ===> x(x+2)(x-1) < 0. The critical numbers of the inequality are -2, 0, and 1. They partition the real number line into 4 parts. Use test numbers -3, -1, 0.5, and 2 in each respective part.
For (, -2), x(x+2)(x-1) < 0.
For (-2,0), x(x+2)(x-1) > 0.
For (0,1), x(x+2)(x-1) < 0.
For (1, ), x(x+2)(x-1) > 0.
The solution set is then the union (, -2)U (0,1).
