Answer:
6(x + 9) (x + 9)
or

Step-by-step explanation:

Greatest common factor of 6, 108, and 486:
6 x 1 = 6
6 x 18 = 108
6 x 81 = 486
GCF: 6
so:


factors to:
(x + 9) (x + 9)
because:
9 x 9 = 81
9 + 9 = 18
So:
It factors completely too:
6(x + 9) (x + 9)
or

1. 0.5625
2. 144
3. -2
4. -16
The answer is going to be the second one
