(a2 + 2a + 1)(a + 1)

= a^3 + 2a^2 + a + a^2 + 2a + 1

= a^3 + 3a^2 + 3a + 1

$\text{The product is }a^3+3a^2+3a+1$

Step-by-step explanation:

$\text{Given the expression }(a^2 + 2a + 1)(a + 1)$

we have to find the product.

(a^2 + 2a + 1)(a + 1)

Opening the brackets

a^2(a+1)+2a(a+1)+1(a+1)

Using distributive property, a.(b+c)=a.b+a.c

(a^3+a^2)+(2a^2+2a)+(a+1)

Combining like terms

a^3+(a^2+2a^2)+(2a+a)+1

a^3+3a^2+3a+1

which is required polynomial.

Option 2 is correct.
