Well, when I took an old SAT I to practice for the PSAT, one of the
questions in one of the math sections asked something about "which of
these equations has one integer root?" and gave something like 2x+1=0,
3x^2-2=0, and 4x^3-3=0 (I'm not sure of the coefficients). Instead of
using the quadratic for the second one, and thinking over/plugging in
random values for the third, I simply used the POLY function on my TI-85
and had the correct answer in maybe 10 seconds...
