I observed an Algebra class recently where students were trying to multiply two polynomials, (x + 5) and (3x2 - 5x - 4). And as I roamed the room, I noticed several students who were stuck because ...

Video – Expanding double brackets Watch this video to see how to expand double brackets using the grid or FOIL method.

But algorithms show up in more advanced topics, too, like the “FOIL” method learned in Algebra 1 for multiplying binomials, such as (x +2) * (3x - 6): You start by multiplying with the first ...

Revise collecting like terms, how to use algebraic notation and symbols correctly, simplifying expressions, and multiplying a single term over a bracket.
