13-squaredx1-squared Explain how the diagrams show how to work out 13 times 13 and (x+1) times (x+1).

Draw similar diagrams for 15 times 15 and (x+2) times (x+2).

Draw your own diagrams and use the same method to find the algebraic expressions for  (x + 3)^2 and (2x + 5)^2 and work out the expansion of (a + b)(c + d).
