You Must Still Think Yourself, CAS Can Only Help

Have the class learn about and make conjectures about a line intersecting a cubic.  In this making conjectures about a line intersecting a cubic lesson, students draw lines that intersect a cubic at three different points.  Students determine the sum of the intersection points.  Students repeat the process for various cubics.  Students make a conjecture that the sum of the three x-values of the intersection points is always -a.

Lesson Planet has been one of the primary ingredients for the mortar I need in order to successfully provide a positive learning environment for my students. It saves me the effort of weeding through the abyss of internet resources available and provides quality resources from qualified and experienced teachers. Thank You!!!
