Which of the following values of x makes the rational expression below equal
to zero?
6x-12
x-7

.

Step-by-step explanation:

The given rational expression is .

To find the x-value that makes the rational expression zero, we equate the whole function or just the numerator to zero and solve for x.

This implies that:

.

.

.

Divide both sides by 6

.

Therefore x=2 makes the rational expression zero.
