Chapter 5: What does factorising x^2 + bx + c mean (visually)?

Reference: IT Exploration Worksheet

Part 1:

LHS = a2 + 2a + 1
RHS = (a+1)(a+1), which can be rewritten as (a+1)2


Part 2:
View the following animation to understand learn how the rectangular pieces are assembled.
Did you notice there is a systematic way of organising the rectangular piecs?

Look at all THREE examples

Part 3:
Generate your own polynomials to factorise using the manipulatives
Update your diagrams and answers in the worksheet.

Select "Tiles (Natural #)" to generate 3 polynomials
