How many complex roots does a 4th degree polynomial have?
A fourth-degree polynomial has, at most, four roots.- If a degree 4 polynomial has 4 real roots, then it must have at least 3 local extremes, so its derivative must have 3 real roots; by repeating this argument, its second derivative must have 2 real roots. But in fact, the second derivative of this function is 12((x?1)2+1), which is clearly positive everywhere.
