Answer:
c
Step-by-step explanation:
Because you can't have multiple x-values. You can only have multiple y-values.
First see you can factor out 4. What is left is x^2 + 6x - 16.
That can be factored as (x+8)(x-2) so the total factorization is
4(x+8)(x-2)
Measure it hope that helps if not that's on me
