Summary for 30/08/10

Yeo Jun Peng (22)- 30/8/10
If a question asked you about drawing the Line Of Symmetry, it means cutting the graph into two exactly similar parts facing each other like a mirror image.


(a+b)(a+b)=(a)(a)+(2ab)+(b)(b) AND (a-b)(a-b)=(a)(a)-(2ab)+(b)(b) are called: Perfect Squares
(a+b)(a-b)=(a)(a)-(b)(b) are called: Difference Of 2 Squares

NOTE*: (a+b)(a+b)≠(a)(a)+(b)(b)

Good luck for your test on Friday:)
