ab: Summary: An algorithm is presented for factorising a quadratic expression
to facilitate instruction and learning. It appeals to elementary
geometry which may provide better insights to some students or
teachers. There have been many methods for factorising a quadratic
expression described in school text books. However, students often seem
to struggle with grasping this skill. Anwar H. Joarder presents some
geometric explanation with the hope that it will help visualise the
steps of the solution. (ERIC)
