                        TRIPLICATE 


If x-->0^+  (in other words, if x approaches 0 from the right), then x^2 approaches 0 from the right, too.


If x-->0^-  (in other words, if x approaches 0 from the left), then (x^3-x) approaches 0 from the left  (sic !).


THEREFORE,  the  ANSWER  to the problem's question is  a*b.

Solved, with complete explanation.
