Question

identities of polynomials​

Answer 1

Step-by-step explanation:

Here are some most commonly used identities of polynomials:

• (a + b + c)2 = a2 + b2 + c2 + 2ab + 2bc + 2ca.
• (a + b)3 = a3 + 3a2b + 3ab2 + b. ...
• (a − b)3 = a3 − 3a2b+ 3ab2 − b. ...
• (a)3 + (b)3 = (a + b)(a2 − ab + b2)
• (a)3 − (b)3 = (a − b)(a2 + ab + b2)
• (a)3 + (b)3 + (c)3 − 3abc = (a + b + c)(a2 + b2 + c2 − ab − bc−ca)

Answer 2

Answer:

• Here are some most commonly used identities of polynomials:

1. (a + b + c)2 = a2 + b2 + c2 + 2ab + 2bc + 2ca.
2. (a + b)3 = a3 + 3a2b + 3ab2 + b. ...
3. (a − b)3 = a3 − 3a2b+ 3ab2 − b. ...
4. (a)3 + (b)3 = (a + b)(a2 − ab + b2)
5. (a)3 − (b)3 = (a − b)(a2 + ab + b2)
6. (a)3 + (b)3 + (c)3 − 3abc = (a + b + c)(a2 + b2 + c2 − ab − bc−ca)
