Factoring Polynomials Scavenger Hunt This scavenger hunt covers the factoring of integers, monomials, and polynomials. Scroll down to questions and their links to help you learn more about factoring polynomials. Bookmark this page so you can return to it quickly. Have fun learning! In addition, you will be asked to provide a “Print-screen” of some of the pages. For directions on how to provide this copy click here. Find the answer to the questions below. Open Microsoft Word and type your answers. Some of your answers may have to be hand written. Once you have finished the scavenger hunt, print out your word processing document and turn it in along with any hand written explanations.
