1. (α+b)²= α²+2αb+b²
2. (α+b)²= (α-b)²+4αb 
3. (α-b)²= α²-2αb+b²
4. (α-b)²= (α+b)²-4αb
5. α² + b²= (α+b)² - 2αb.
6. α² + b²= (α-b)² + 2αb.
7. α²-b² =(α + b)(α - b)
8. 2(α² + b²) = (α+ b)² + (α - b)²
9. 4αb = (α + b)² -(α-b)²
10. αb ={(α+b)/2}²-{(α-b)/2}².
11. (α + b + ¢)² = α² + b² + ¢² + 2(αb + b¢ + ¢α).
12. (α + b)³ = α³ + 3α²b + 3αb² + b³.
13. (α + b)³ = α³ + b³ + 3αb(α + b).
14. (α-b)³= α³- 3α²b+3αb²-b³.
15. α³ + b³ = (α + b) (α² -αb + b²).
16. α³ + b³ = (α+ b)³ - 3αb(α+b).
17. α³ -b³ = (α -b)  (α² + αb + b²).
18. α³ -b³ = (α-b)³  + 3αb(α-b).
