Zeros of a Function #6

For the Rational Zero Test, we first find all the possible zeros using P/S then test the zeros using the remainder theorem. A hint would be to graph to see all the possible points. The Rational Zero Tsst gives you the possibility of all the rational zeros. Once you find one, you can do synthetic division. Just like last week, we might have to use synthetic division multiple times. Since the work it really tedious, the Rational Zero Test is the best method to use. Remember both positive and negative parts of zeros!
