$\frac{3 x - 12}{9 - x}$

Step 1

Factor $3$ out of $3 x$ .

$\frac{3 (x) - 12}{9 - x}$

Step 2

Factor $3$ out of $- 12$ .

$\frac{3 x + 3 \cdot - 4}{9 - x}$

Step 3

Factor $3$ out of $3 x + 3 \cdot - 4$ .

$\frac{3 (x - 4)}{9 - x}$

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