Select all of the following that are potential roots of p(x) = x4 − 9x2 − 4x + 12? evaluate the function for the given values to determine if the value is a root. p(−2) = p(2) = the value is a root of p(x).

p(-2)= 0

p(2)= -16

the value is -2

Step-by-step explanation:

For any polynomial ,   is a root of the polynomial only if .

To determine which of the given values is a root of the polynomial ,

,

we just have to evaluate the for each of these values and see if the output is zero.

Since , we know that  is  not a root of this polynomial.

Since , we know that  is a root of this polynomial.
