Factor $4 x$ out of $4 x$ .

$4 x (x^{3}) + 4 x (1)$

Factor $4 x$ out of $4 x (x^{3}) + 4 x (1)$ .

$4 x (x^{3} + 1)$

Rewrite $1$ as $1^{3}$ .

$4 x (x^{3} + 1^{3})$

Since both terms are perfect cubes, factor using the sum of cubes formula, $a^{3} + b^{3} = (a + b) (a^{2} - a b + b^{2})$ where $a = x$ and $b = 1$ .

$4 x ((x + 1) (x^{2} - x \cdot 1 + 1^{2}))$
