Factorisation & Expansion - Part 2 (Algebra Basics)

In this lesson, we’ll briefly go through FOIL expansion and factorisation step by step in a general manner. You’ll learn how to expand two brackets using FOIL technique (First, Outer, Inner, Last), and how to reverse the process to factorise expressions correctly. These involve expressions called trinomials, which involve squared terms. This tutorial lesson is perfect for Year 9 students in NZ, or anyone who is learning basic algebra.
