Even though my formula says Dan Keis does not belong on gold, I might put him there since he did so well on these tests.

The problem that only one (at Heritage - none at FHMS) got was: Simplify
 x²+2x-24
____________
    x-4

Now, in order to simplify this, x²+2x-24 must be divisible by x-4.

So the question is: what times (x-4) = x²+2x-24
(x-4)(x+?) = x²+2x-24    Well, what tie -4 = -24? The missing number must be 6.
(x-4)(x+6) = (x-4)x + (x-4)6 = x²-4x + 6x-24 = x²+2x-24 Aha! So

  x²+2x-24      (x-4) (x+6)
____________   =  ____________ =  x+6  Quite simplified!
    x-4               (x-4)
