Algebraic Formulas || Important Formulas of Algebra

Below are the list of all important algebraic formulas.

1. (a+b)² = a²+b²+2ab

2. (a-b)² = a²+b²-2ab

3. a²-b² = (a-b)(a+b)

4. (a+b)³= a³+b³+3ab(a+b)

5. (a-b)³= a³-b³-3ab(a-b)

6. a³+b³ = (a+b)(a²+b²-ab)

7. a³-b³ = (a-b)(a²+b²+ab)

8. (a+b+c)² = a²+b²+c²+2ab+2bc+2ca

9. a³+b³+c³-3abc = (a+b+c)(a²+b²+c²-ab-bc-ca)
