Check 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
“Can your child multiply out two brackets like (x + 3)(x − 2) and collect the terms to get x² + x − 6?”
