1 answer

The excluded value of the rational expression 2x+6/4x-8 is the value(s) of x that make the denominator equal to zero. In this case, the excluded value is found by setting 4x-8 equal to zero and solving for x:

4x-8 = 0
4x = 8
x = 8/4
x = 2

So the excluded value of the rational expression is x = 2.
