Factor x^3-8

Factor x^3-8

$x^{3} - 8$

Rewrite $8$ as $2^{3}$ .

$x^{3} - 2^{3}$

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

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

Simplify.

Tap for more steps...

Move $2$ to the left of $x$ .

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

Raise $2$ to the power of $2$ .

$(x - 2) (x^{2} + 2 x + 4)$

$(x - 2) (x^{2} + 2 x + 4)$
