Answer:

Let,

, p(X) = x² - 9

Step-by-step explanation:

______

Firstly

______

Putting x = -3 in the the given equation

p(-3) = x² - 9

= ( -3 )² - 9

= - 9 - 9

= -18

since p(-3) is not equal to 0

Hence , -3 is not a zero of polynomial

--------------------------

Now

Secondly

__________

Putting X = 3 in the equation

p(3) = x² - 9

= 3² - 9

= 9 - 9

= 0

Here,

since p (3) is equal to 0

Hence 3 is a zero of polynomial.
