Abstract

The article focuses on using multiplication grids as a method to simplify the factorisation of quadratic expressions, particularly for secondary school students who may struggle with recalling multiplication facts. It demonstrates how traditional multiplication grids can be adapted to include negative numbers, enabling the factorisation of quadratics with various sign combinations in their terms. The approach extends to quadratics where the coefficient of \(x^2\) is greater than one by using the product-sum method supported by the grid to reduce cognitive load. This method offers an accessible alternative to conventional techniques, aiming to support students’ understanding of a commonly challenging algebraic topic. [Extracted from the article]
