solve the following inequality. write your solutionin interval notation x^3x<0

x(x1)(x+1) < 0
The roots are 1,0,1
Since there are no repeated roots, the graph crosses the axis at each root.
So, y<0 for large x<0, so the intervals are
(oo,1) < 0
(1,0) > 0
(0,1) < 0
(1,oo) > 0
y<0 for x in (oo,1)U(0,1)
