I recently came upon this and was wondering if it's a Solve bug, some notation I'm not familiar with, or just an unfortunate happenstance. When I give Mathematica the equation x^3-8==0, this is what it returns: In[1]:= Out[1]= But if I first factor the polynomial instead: In[2]:= Out[2]= if I use reduce instead of solve In[3]:= Out[3]= My question is: why the different behaviors, and how can I tell in advance which to use? +----------------------------+ | | I understand mine's a risky plan, | Greg Anderson | and your system can't miss | dwarf at wam.umd.edu | but is security, after all a cause | timbwolf at eng.umd.edu | or symptom of happiness. | | +----------------------------+ Dream Theater -- A Matter of Time
