Answer 2

Answer:

they are not the zeros of the polynomial as the required anser doesn't came out to be "zero"

Step-by-step explanation:

x= (-2)

x= (2)

put this into the eq. x4 - 16 in place of X

(-2)4 -16

32 - 16

16 ...it's not the zero

(2)4 - 16

32 - 16

16...it's not the zero...as well
