Napomena autora:

A complete formative lesson with embedded slideshow, mini lecture screencasts, checks for understanding, practice items, mixed review, and reflection. I create these assignments to supplement each lesson of Pearson's Common Core Edition Algebra 1, Algebra 2, and Geometry courses. See also mathquest.net and twitter.com/mathquestEDU.

Vocabulary Review: Use the Distributive Property. Match equivalent expressions.

  • y(y + 2)

  • (2y - 1)(y + 2)

  • y(y² + 3y - 6)

  • -1(y + 2)

  • y³ + 3y² - 6y

  • -y - 2

  • y² + 2y

  • 2y(y + 2) - 1(y + 2)
