You can, for example never foretell what any one man will do, but you can say with precision what an average number will be up to!
We have: [3x^2(x-2) - x + 2] / (x-2)If x cannot equal 2, the [3x^2(x-2) - x + 2] / (x-2) =
A. 3x^2 - x + 2
B. 3x^2 + 1
C. 3x^2
D. 3x^2 - 1
E 3x^2 - 2
Notice that we can rewrite - x + 2 as - 1(x+2)
So, [3x^2(x-2) - x + 2] / (x-2) = [3x^2(x-2) - 1(x+2)] / (x-2)
= [(3x^2 - 1)(x+2)] / (x+2)
= 3x^2 - 1
= D
