B.O.B.- "Cool"

The unit on polynomials has been my favorite so far.  I had no idea that you could use polynomials in long division.  If you know one zero, it is “cool”   how you can factor it into the polynomial and then find the rest of the zeros.  For example, in the problem:   x³-4x²-17x+60/x-3, after factoring the root of 3 into the cubic, you find the other two zeros to be 5, and -4. I find the long division of polynomials to be a lot easier to understand than other factoring techniques, and for me, a lot more efficient. Hopefully the next unit will be just as “cool”.
