Expanding Double Brackets
Expand products of two or more binomials, e.g., (x + 3)(x - 2) = x² + x - 6, using the grid method or FOIL; simplify the result by collecting like terms
Suggested ages 13–14
Evidence of understanding
- Expand the product of two binomials using a systematic method (grid or FOIL)
- Collect like terms after expansion to simplify the result
- Expand products involving negative terms correctly
Assessment prompt
Can Expanding Double Brackets multiply out two brackets like (x + 3)(x − 2) and collect the terms to get x² + x − 6?
