Use synthetic division to decide whether the given number k is a zero of the given polynomial function.
-$$- \frac { 2 } { 3 } ; f ( x ) = - 3 x ^ { 4 } - 5 x ^ { 2 } - 4$$
A) Yes
B) No

Question

Quizplus · Accepted Answer

Synthetic division shows that substituting $ k = -\frac{2}{3} $ into the polynomial does not yield a remainder of zero, indicating that it is not a zero of the polynomial.
