$\frac{a - b}{a^{2} - b^{2}}$

Step 1

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

$\frac{a - b}{(a + b) (a - b)}$

Step 2

Cancel the common factor of $a - b$ .

Step 2.1

Cancel the common factor.

$\frac{a - b}{(a + b) (a - b)}$

Step 2.2

Rewrite the expression.

$\frac{1}{a + b}$
