Three by Three Systems: More than Just a Point
February 2006, Volume 99, Issue 6, Page 419
This article focuses on solving three by three systems.
Building on their knowledge of the three possible outcomes of solving 2x2
systems of equations, students use three-dimensional geometric figures to
investigate the eight possible outcomes for solving 3x3 systems of equations.
The article features problems, discussion and assessment information.
