f(x)=x^4-3x^3+5x^2-2x+5=0 has 4 non real zeros which are

x=-0.1386212+/-1.002153 i

x=1.638621+/-1.483234 i

highly approximate. You may check it out.

Descartes rule of signs=>

f(+)=+-+-+ has at most 4 +ve real zeros

f(-)=+++++ has at most 0 -ve real zeros

In fact, f(x)=0 has no real zero.

x=1-i is not a zero. What do you mean by posting it?
