Step 1.1.1

Factor out the GCF of $x$ from the expression $x^{3}$ .

$x (x^{2}) + 2 x^{2} + x$

Step 1.1.2

Factor out the GCF of $x$ from the expression $2 x^{2}$ .

$x (x^{2}) + x (2 x) + x$

Step 1.1.3

Factor out the GCF of $x$ from the expression $x$ .

$x (x^{2}) + x (2 x) + x (1)$

Step 1.2

Since all the terms share a common factor of $x$ , it can be factored out of each term.

$x (x^{2} + 2 x + 1)$

Step 2

Factor using the perfect square rule.

Step 2.1

Rewrite $1$ as $1^{2}$ .

$x (x^{2} + 2 x + 1^{2})$

Step 2.2

Check that the middle term is two times the product of the numbers being squared in the first term and third term.

$2 x = 2 \cdot x \cdot 1$

Step 2.3

Rewrite the polynomial.

$x (x^{2} + 2 \cdot x \cdot 1 + 1^{2})$

Step 2.4

Factor using the perfect square trinomial rule $a^{2} + 2 a b + b^{2} = {(a + b)}^{2}$ , where $a = x$ and $b = 1$ .

$x ({(x + 1)}^{2})$
