$\frac{(a + h^{2} + 1) - (a^{2} + 1)}{h}$

Step 1

Apply the distributive property.

$\frac{a + h^{2} + 1 - a^{2} - 1 \cdot 1}{h}$

Step 2

Multiply $- 1$ by $1$ .

$\frac{a + h^{2} + 1 - a^{2} - 1}{h}$

Step 3

Subtract $1$ from $1$ .

$\frac{a + h^{2} - a^{2} + 0}{h}$

Step 4

Add $a + h^{2} - a^{2}$ and $0$ .

$\frac{a + h^{2} - a^{2}}{h}$

$[\begin{array}{c} x^{2} & \frac{1}{2} \\ \sqrt{π} & \int x d x \end{array}]$
