Answer:
D
Explanation:
The Rational root theorem states that the possible roots ( zeros) of a polynomial are of the form
( plus or minus ) factors of the constant term divided by the factors of the leading coefficient.
For x³ - 3x² + 27x - 8
The factors of constant term (- 8) are ± 1, 2, 4, 8
The coefficient of the leading term x³ is 1
Hence possible zeros are
± (
) = ± 1, ± 2, ± 4, ± 8 → D
