**Factorization of Polynomials Formula**

* 1 (a+b)²=*a²+b²+2ab

* 2(a+b)²=*(a+b)(a+b)

* 3(a-b)²=*a²+b²-2ab

* 4(a-b)²=*(a+b)(a-b)

* 5(a+b+c)²=*a²+b²+c²+2ab+2bc+2ca

** 6(a+b+c)²=**(a+b+c)(a+b+c)

* 7(a+b)³=*a³+b³+3ab(a+b)

* 8(a+b)³=*a³+b³+3a²b+3ab²

* 9(a-b)³ =* a³-b³-3a²b+3ab²

* 10(a-b)³ =* a³-b³-3ab(a-b)

* 11 a²+b²=*(a-b)²+2ab

* 12(a+b)²=*(a-b)²+4ab

* 13(a-b)²=*(a+b)²-4ab

* 14 a³-b³=*(a-b)(a²+b²+ab)

* 15 a³+b³=*(a+b)(a²+b²-ab)

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

* 17 a³+b³+c³-3abc=*½(a+b+c)(a-b)²+(b-c)²+(c-a)²

**18 (x+a)(x+b)=**x²+(a+b)x+ab

What kind of formula it is? How does it look like? Can you please provide a couple of samples? I will be so thankful for the answer.
