(b + 2)(b - 8)
The AxB interaction has (nA - 1)*(nB - 1) degrees of freedom where there are nA levels of A and nB levels of B.
b
(a+b)(a-b)
There's not enough information to determine that.
-8
a^2 - b^2 = (a - b)(a + b) a^2 + b^2 doesn't factor rationally.
There is an established statistical point for most comparisons or measurements that is so small that differences at or below it are considered to be "random", "predictable", or "meaningless". If a difference between A and B exceeds this point, it is said to be "significant", which does not necessarily mean "important" or "huge" - just "significant".
Not sure about the greatest commom factor, but the greatest common factor is b.
