MA10-03
This lesson is coming soon.
In this lesson
Expand the product of three or more linear factors by chaining pairwise expansion in two stages.
What it covers
- Expanding a product of three (or more) linear factors by expanding a pair first, then multiplying that result by the remaining bracket
- Checking working carefully at the second-stage multiplication

For teachers
This GCSE Maths lesson teaches expanding three or more brackets. By the end, students should be able to expand the product of three or more linear factors by chaining pairwise expansion in two stages. It works through two worked examples and the mistakes examiners report.
