Given,
We have,
- To check whether x = 2 is a zero of p(x)
So,
- If taking p(x) as p(2) is equal to zero, then, x = 2 will be zero of p(x).
Now,

Answer:
No
Step-by-step explanation:
p (x)= x^3 - 3x^2- x -6
Now,
p (2)= (2)^3 - 3 (x)^2- 2- 6
p (2)= 8 - 3×4 - 8
p (2)= -12 not equal to 0
Hence, 2 is not a zero of the given polynomial.
