A step-by-step guide how to build a GeoGebra tool to explore the effect of factors on the shape of a polynomial. A fun and interesting tool to support learning the properties of zeroes of a polynomial - especially helpful for exploring the effect of multiple (repeat) zeroes. Once they have built the tool, students can extend to higher degree polynomials or add translations.
