Answer: A. (x + 4)(x - 3)

(x + 4)(x - 3) is the only answer that cannot be factored.


2 can be factored out of 2x + 4
(2x + 4)(x - 3)
factored as 2(x + 4)(x - 3)


this one isn’t even multiplication:
(x - 2) + (x + 3)
It can be written as 2x +1


3 can be factored out of 3x -9
(x - 2)(3x - 9)
It factors into 3(x - 2)(x - 9)


But nothing can be factored out of (x + 4)(x - 3)

Answer:

a

Step-by-step explanation:

x+4 and x-3 cant be simplified any further therefore making it completely factored.
