Use the Rational Zero Test to find all rational zeros of f. Write f(x) as the product of linear factors, one for each rational zero, and another factor g(x). If g(x) has degree 2, find its zeros by factoring or by using the quadratic formula. If g(x) has degree 3 or greater, use the Bounds Test, if possible, to find lower and upper bounds for the zeros of g. Approximate the remaining zeros graphically.
