It can have 1, 2 or 3 unique roots.
5, Using complex numbers you will always get 5 roots.
According to the rational root theorem, which of the following are possible roots of the polynomial function below?F(x) = 8x3 - 3x2 + 5x+ 15
Sort of... but not entirely. Assuming the polynomial's coefficients are real, the polynomial either has as many real roots as its degree, or an even number less. Thus, a polynomial of degree 4 can have 4, 2, or 0 real roots; while a polynomial of degree 5 has either 5, 3, or 1 real roots. So, polynomial of odd degree (with real coefficients) will always have at least one real root. For a polynomial of even degree, this is not guaranteed. (In case you are interested about the reason for the rule stated above: this is related to the fact that any complex roots in such a polynomial occur in conjugate pairs; for example: if 5 + 2i is a root, then 5 - 2i is also a root.)
Such an equation has a total of six roots; the number of real roots must needs be even. Thus, depending on the specific equation, the number of real roots may be zero, two, four, or six.
A fourth degree polynomial function can have up to four unique roots. However, the actual number of unique roots can be fewer, depending on the polynomial's coefficients and the nature of its roots. Roots can be real or complex, and some roots may be repeated (multiplicity). Thus, the number of unique roots can range from zero to four.
It can have 1, 2 or 3 unique roots.
A polynomial of degree ( n ) can have at most ( n ) unique roots. This is due to the Fundamental Theorem of Algebra, which states that a polynomial of degree ( n ) has exactly ( n ) roots in the complex number system, counting multiplicities. Therefore, if all the roots are distinct, the maximum number of unique roots is equal to the degree of the polynomial.
4, the same as the degree of the polynomial.

5, Using complex numbers you will always get 5 roots.
A sixth-degree polynomial function can have up to six unique roots. However, the actual number of unique roots can be fewer than six, depending on the specific polynomial and whether some roots are repeated (multiplicity). According to the Fundamental Theorem of Algebra, the total number of roots, counting multiplicities, will always equal the degree of the polynomial, which is six in this case.
A seventh-degree polynomial function can have up to 7 unique roots, according to the Fundamental Theorem of Algebra. However, some of these roots may be complex or repeated, meaning the actual number of distinct roots can be fewer than 7. In total, the polynomial can have anywhere from 0 to 7 unique roots.
