To find the possible rational zeros of the polynomial function \( f(x) = 3x^4 - 11x^3 - x^2 + 19x + 6 \), we can use the Rational Root Theorem. This theorem states that any rational zero, expressed as
, must have
as a factor of the constant term and
as a factor of the leading coefficient.For the polynomial \( f(x) = 3x^4 - 11x^3 - x19x + 6 \):1. The constant term is
.2. The leading coefficient is
.First, list the factors of the constant term
:
Next, list the factors of the leading coefficient
:
Now, form all possible fractions
where
is a factor of the constant term and
is a factor of the leading coefficient:
So, the list of all possible rational zeros is:
Therefore, the possible rational zeros of the polynomial \( f(x) = 3x^4 - 11x^3 - x^2 + 19x + 6 \) are:
