Factor w^3-125

$w^{3} - 125$

Step 1

Rewrite $125$ as $5^{3}$ .

$w^{3} - 5^{3}$

Step 2

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 $a = w$ and $b = 5$ .

$(w - 5) (w^{2} + w \cdot 5 + 5^{2})$

Step 3

Simplify.

Move $5$ to the left of $w$ .

$(w - 5) (w^{2} + 5 w + 5^{2})$

Raise $5$ to the power of $2$ .

$(w - 5) (w^{2} + 5 w + 25)$
