Step 1.1

Factor $a$ out of $a^{2}$ .

$\frac{a \cdot a - 2 a}{(a + 5) (a - 2)}$

Step 1.2

Factor $a$ out of $- 2 a$ .

$\frac{a \cdot a + a \cdot - 2}{(a + 5) (a - 2)}$

Step 1.3

Factor $a$ out of $a \cdot a + a \cdot - 2$ .

$\frac{a (a - 2)}{(a + 5) (a - 2)}$

$\frac{a (a - 2)}{(a + 5) (a - 2)}$

Step 2

Cancel the common factor of $a - 2$ .
