Step 1.1

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

$\frac{d \cdot d - 4 d}{d - 4}$

Step 1.2

Factor $d$ out of $- 4 d$ .

$\frac{d \cdot d + d \cdot - 4}{d - 4}$

Step 1.3

Factor $d$ out of $d \cdot d + d \cdot - 4$ .

$\frac{d (d - 4)}{d - 4}$

$\frac{d (d - 4)}{d - 4}$

Step 2

Cancel the common factor of $d - 4$ .
