Step 1.1

One to any power is one.

$a_{1} = \frac{1 - 1}{1^{2} + 1}$

Step 1.2

Subtract $1$ from $1$ .

$a_{1} = \frac{0}{1^{2} + 1}$

$a_{1} = \frac{0}{1^{2} + 1}$

Step 2

Simplify the denominator.

Step 2.1

One to any power is one.

$a_{1} = \frac{0}{1 + 1}$

Step 2.2

Add $1$ and $1$ .

$a_{1} = \frac{0}{2}$

$a_{1} = \frac{0}{2}$

Step 3

Divide $0$ by $2$ .

$a_{1} = 0$
