Maths Equations

Some Important Maths Equations
1. a(b+c) = ab + ac
2. (a+b) ^2 = a ^2 + 2ab + b ^2
3. (a-b) ^2 = a^ 2 -2ab + b ^2
4. (a+b)^ 2 = (a-b)^ 2 + 4ab
5. (a-b) ^2 = (a+b) ^2 - 4ab
6. (a-b) (a+b) = a ^2 - b ^2
7. (a+b) ^3 = a^ 3 + 3ab(a+b) + b^ 3
8. (a-b) ^3 = a ^3 - 3ab(a-b) - b^ 3
9. a ^3 + b ^3 = (a+b) (a ^2 - ab + b ^2 )
10. a^ 3 - b ^3 = (a-b) (a ^2 + ab + b^ 2 )
11. (a ^3 - b^ 3 ) / (a^ 2 + ab + b^ 2 ) = a-b
12. (a ^3 + b ^3 ) / (a ^2 - ab + b^ 2 ) = a+b
