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.

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
