Factor 2x^3+2

$2 x^{3} + 2$

Step 1

Factor $2$ out of $2 x^{3} + 2$ .

Factor $2$ out of $2 x^{3}$ .

$2 (x^{3}) + 2$

Factor $2$ out of $2$ .

$2 (x^{3}) + 2 (1)$

Factor $2$ out of $2 (x^{3}) + 2 (1)$ .

$2 (x^{3} + 1)$

Step 2

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

$2 (x^{3} + 1^{3})$

Step 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 $b = 1$ .

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

Step 4

Factor.

Simplify.

Multiply $- 1$ by $1$ .

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

One to any power is one.

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

Remove unnecessary parentheses.

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