Answer:
A.
Step-by-step explanation:
Hi there!
By factoring the trinomial, we end with (x-9)(x-4)
However, we aren’t done yet. To find the zeros, set each expression equal to zero, so it looks something like this.
0 = x - 9
0 = x - 4
Using orders of operations, x = 9 and x = 4
Therefore, A is your answer.
I hope this helps!
