$$\frac{3x^2 - 12x}{2x - 7} \div \frac{x - 4}{2x - 7}$$

You have to reciprocate the second fraction then multiply:

$$\frac{3x^2 - 12x}{2x - 7} \times \frac{2x - 7}{x - 4}$$

Also, you have to cancel factors of one:

$$\frac{3x\cancel{(x - 4)}}{\cancel{2x - 7}} \times \frac{\cancel{2x - 7}}{\cancel{x - 4}}$$
