CHAPTER AT A GLANCE
We Distribute, Yet Things Multiply
•Unit: Algebra
•Board weightage: Multiplication of algebraic expressions and the identities (a + b)², (a − b)² and (a + b)(a − b) give regular 2-mark, 3-mark and 4-mark questions (please check the latest sample paper)
•Key ideas from the textbook: how a product changes, the distributive property, multiplying two expressions, Identities 1, 1A, 1B and 1C, fast multiplication, spotting mistakes, area and pattern problems
•Most scoring part: expanding products and using the identities to compute squares and products quickly
•Time to revise: about 60 minutes
