Answer:
X = 3 is the solution of f(x) and is the zero of the polynomial f(x).
Step-by-step explanation:
Please refer to the picture above for more details.
Basically, to find out if x=a (where a is a unknown) is a solutiom of f(x), u need to substitute x with a to find out if the final answer is 0 or not.
If the final answer is 0, 'a' is a solution of f(x)
If the final answer is not 0 (can be any positive or negative value), 'a' is not the answer.
