Expanding Double Brackets
MA10-02
This lesson is coming soon.
In this lesson
Expand the product of two binomials using a grid or FOIL method, correctly tracking the sign of every term including the combined middle term.
What it covers
- Expanding the product of two binomials via a grid or FOIL method
- Combining the two middle terms correctly, including when the two brackets contain two different variables
- Recognising when a context needs two brackets MULTIPLIED (area-type) rather than simply added together

For teachers
This GCSE Maths lesson teaches expanding double brackets. By the end, students should be able to expand the product of two binomials using a grid or FOIL method, correctly tracking the sign of every term including the combined middle term. It works through three worked examples and the mistakes examiners report.
