1. a(b+c) = ab + ac

2. (a+b)2 = a2 + 2ab + b2

3. (a-b)2 = (a+b)2 - 4ab
4. (a-b)2 = a2-2ab + b2

5. (a+b)2 = (a-b)2 + 4ab

6. (a+b)3 = a3 + 3ab(a+b) + b3

7. (a-b) (a+b) = a2 - b2


8. (a3 - b3) / (a2 + ab + b2) = a-b

9. (a-b)3 = a3 - 3ab(a-b) - b3


10
. (a3 + b3) / (a2 - ab + b2) = a+b
11. a3 - b 3 = (a-b) (a2 + ab + b2)


12
. a3 + b 3 = (a+b) (a2 - ab + b2)
