Expanding Double Brackets

PROCEDURAL
MathematicsAlgebra|Ages 13—14|ID: mt_KhS7K1Mgrw

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

Mastery Evidence

  • 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 [child] multiply out two brackets like (x + 3)(x − 2) and collect the terms to get x² + x − 6?”
