Basic Math Examples

${(g)}^{2} - 1$

Step 1

Remove parentheses.

$g^{2} - 1$

Step 2

Rewrite $1$ as $1^{2}$ .

$g^{2} - 1^{2}$

Step 3

Since both terms are perfect squares, factor using the difference of squares formula, $a^{2} - b^{2} = (a + b) (a - b)$ where $a = g$ and $b = 1$ .

$(g + 1) (g - 1)$
