Question about how to solve: Determine the zeros of f(x) = x4 – x3 + 7x2 – 9x – 18.
I am solving this problem using all of the polynomial ways such as decartes rule, fundamental therom and rational root. But it seems when I solve it that way, I either come up one answer short or a completely different answer from what I see everyone else get. How would you solve this and what is the answer?
