Answer:
(9a^2b^2(2ab - 3b + 4a).
Step-by-step explanation:
Take out the GCF.
The GCF is 9a^2b^2 so the factors are
(9a^2b^2(2ab - 3b + 4a).
As we could "drag" these together, we could then do it the easy way.
56
+56
+56
-------
168
------------------------
Or we could also do the following:
56

3:
6

3= 18.
Carry the one.
5

3 = 15+1 (which was carried). = 16
(16+8) =
168
