Question

check whether -3,3 are the zero of polynomial of x2-9​

Answer 1

Answer:

-3(2)-9

-6-9

-15

So, no it is not

3(2)-9

6-9

-3

So, no it is not

Answer 2

Answer:

When x = -3

x²-9 = (-3)²-9 = 9-9 = 0

Therefore it is a zero of the polynomial.

When x = 3

x²-9 = 3²-9 = 0

Therefore it is a zero of the polynomial.
