Answer:
Prime
Step-by-step explanation:
This expression is actually impossible to factor. To get rid of the middle term, you would need two equal and opposite x values, such as in (x+4y)(x-4y). However, in that case, the expanded expression would be x^2-16y^2, not plus. If you go for the first option, then you are left with a middle term, such as 8xy. Therefore, this expression is prime. Hope this helps!
