yes the only way a polynomial function can have complex roots is if they come in conjugate pairs (like a+i*b, and a-i*b).
A first order polynomial function will have 1 real root.
A 2nd order polynomial function will have 2 complex or 2 real roots.
A 3rd order polynomial function will either have 4 complex, 2 real + 2 complex, or 4 real roots.
A 4th order polynomial function will either have 4 complex + 1 real, 2 complex + 3 real, or 5 real roots.
trolling? or tired?
total number of roots of any polynomial of degree n is n (counting multiplicities)
any polynomial of degree n with real coefficients and n being odd has at least one real root
probably tired i guess
seems you switched from 3rd order to 4th order in the middle of the line
