Answer:
Associative Property
Step-by-step explanation:
The brackets moved, so it would be associative
1 is not. 2 is. 3 is not. 4 is. 5 is. 6 is. 7 is not. 8 is.
6x² + 48x + 96
6(x² + 8x + 16)
6(x + 4)(x + 4) is your polynomial fully factored so I'm guessing the binomial you're looking for is (x + 4).
