Question 440330: Given that f(x) = x%5E6%2Bx%5E5-6x%5E4%2B7x%5E2-21x-18 has -1 as a zero of multiplicity 2, 2 as a zero, and -3 as a zero, find all other zeros.
I tried using synthetic division, but I am not sure after doing so that it was correct.

You must have typoed, because -1, 2, and -3 are not zeros of f(x) (you can easily check by replacing x with the values above).
