Answer 2

$\mathbf{Let \: n \: be \: a \: positive \: integer \: and \: x, \: a \: be \: real \: numbers}$

$\mathsf\red{{(x+a)}^{n} \: = \: ^{n}C_{0}.{x}^{n}.{a}^{0} \: + \: ^{n}C_{1}.{x}^{n-1}.{a}^{1} \: + \: ^{n}C_{2}.{x}^{n-2}.{a}^{2} \: + \: ....... \: + \: ^{n}C_{r}.{x}^{n-r}.{a}^{r} \: + \: ...... \: + ^{n}C_{n}.{x}^{0}.{a}^{n}}$

$\mathsf{{(x+a)}^{n} \: = \: \sum\limits_{i=0}^{n} \: ^{n}C_{r}.{x}^{n-r}.{a}^{r}}$
