$g^{3} + 64$

Step 1

Rewrite $64$ as $4^{3}$ .

$g^{3} + 4^{3}$

Step 2

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 $a = g$ and $b = 4$ .

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

Step 3

Step 3.1

Multiply $4$ by $- 1$ .

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

Step 3.2

Raise $4$ to the power of $2$ .

$(g + 4) (g^{2} - 4 g + 16)$
