Question

factorization of algebraic expression a - b² = a²b + b ² - 2ab​

Answer 1

Answer:

Step-by-step explanation:

(a-b)²=a²+b²-2ab

• it is an algebraic identity and its formula can't be changed

• there are 9 algebraic identities

1. (a+b)²=a²+b²+2ab
2. (a-b)²=a²+b²-2ab
3. (a+b)(a-b)=a²-b²
4. (a+b+c)²=a²+b²+2ab+2bc+2ac
5. (a+b)³=a³+b³+3ab(a+b)
6. (a-b)³=a³-b³+3ab(a-b)
7. a³+b³=(a+b)(a²-ab+b²)
8. a³-b³=(a-b)(a²+ab+b²)
9. a³+b³+c³-3abc=(a+b+c)(a²+b²+c²-ab-bc-ca)
