Answer:
The answer to your question is letter B.
Explanation:
To solve this question we just look at the graph and look for where it intercepts the x-axis.
We see that it intercept the graph in x = -3 and x = 3
So, we express this solutions as factors
x = -3 = (x + 3) and x = 3 = (x - 3)
These are the factors (x + 3) ( x - 3)
