$a_{3} = \frac{3^{2} - 9}{3^{2} + 9}$

Step 1

Simplify the numerator.

Tap for more steps...

Raise $3$ to the power of $2$ .

$a_{3} = \frac{9 - 9}{3^{2} + 9}$

Subtract $9$ from $9$ .

$a_{3} = \frac{0}{3^{2} + 9}$

$a_{3} = \frac{0}{3^{2} + 9}$

Step 2

Simplify the denominator.

Tap for more steps...

Raise $3$ to the power of $2$ .

$a_{3} = \frac{0}{9 + 9}$

Add $9$ and $9$ .

$a_{3} = \frac{0}{18}$

$a_{3} = \frac{0}{18}$

Step 3

Divide $0$ by $18$ .

$a_{3} = 0$
