Step 1.1

Split the limit using the Sum of Limits Rule on the limit as $h$ approaches $0$ .

$\frac{lim_{h \to 0} {(1 + h)}^{2} - lim_{h \to 0} 1}{h}$

Step 1.2

Move the exponent $2$ from ${(1 + h)}^{2}$ outside the limit using the Limits Power Rule.

$\frac{{(lim_{h \to 0} 1 + h)}^{2} - lim_{h \to 0} 1}{h}$

Step 1.3

Split the limit using the Sum of Limits Rule on the limit as $h$ approaches $0$ .

$\frac{{(lim_{h \to 0} 1 + lim_{h \to 0} h)}^{2} - lim_{h \to 0} 1}{h}$

Step 1.4

Evaluate the limit of $1$ which is constant as $h$ approaches $0$ .

$\frac{{(1 + lim_{h \to 0} h)}^{2} - lim_{h \to 0} 1}{h}$

Step 1.5

Evaluate the limit of $1$ which is constant as $h$ approaches $0$ .

$\frac{{(1 + lim_{h \to 0} h)}^{2} - 1 \cdot 1}{h}$

Step 2

Evaluate the limit of $h$ by plugging in $0$ for $h$ .

$\frac{{(1 + 0)}^{2} - 1 \cdot 1}{h}$

Step 3.1.1

Add $1$ and $0$ .

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

Step 3.1.2

One to any power is one.

$\frac{1 - 1 \cdot 1}{h}$

Step 3.1.3

Multiply $- 1$ by $1$ .

$\frac{1 - 1}{h}$

Step 3.1.4

Subtract $1$ from $1$ .

$\frac{0}{h}$

Step 3.2

Divide $0$ by $h$ .

$0$
