Answer 2

Answer:

$\huge\star\underbrace{\mathtt\red{⫷❥ᴀ᭄} \mathtt\green{n~ }\mathtt\blue{ §} \mathtt\purple{₩}\mathtt\orange{Σ} \mathtt\pink{R⫸}}\star\:$

Step-by-step explanation:

$\huge\underline{Equation→}$

$({x + 1})^{3}$

$\huge\underline{Identity→}$

=>So let x be ‘a’ and 1 be ‘b’

$({a + b})^{3} = {a}^{3} + {b}^{3} + 3ab(a + b)$

SUBSTITUTING THE VALUES→

=>(x+1)^3=(x)^3+(1)^3+3(x)(1)(x+1)

=x^3+1+3x(x+1)

=x^3+1+3x^2+3x.

☞So x^3+3x^2+3x+1 is the required answer.
