This self checking worksheet studies factors of polynomials on the front and remainder theorem on the back. The Factor Theorem uses the student's knowledge of graphs of polynomial functions and the degree of the polynomial. The student must find all POSSIBLE sets of factors for each polynomial. Note: The student is not looking for only the exact solution. There may be more than one possible solution which is what makes this worksheet tricky. On the back of the worksheet, the student is given a polynomial and a factor. The student must circle 'yes' or 'no' to tell whether the given factor is one of the factors of the polynomial. The solutions will reveal the answer to a riddle.
