Given:


((n-6)(5n+4))/(n(n-6)(7n+8))

Required:

We need to find the excluded values of the domain.

Step-by-step explanation:

Cancel out the common factor (n-6).


((5n+4))/(n(7n+8))

The excluded points can be found by equating the numerator of the given expression equal to zero.


n(7n+8)=0
n=0\text{ and }7n+8=0

We get n =0 is one of the excluded points

Consider the equation 7n+8=0.

Subtract 8 from both sides.


7n=-8
n=-(8)/(7)

n=-8/7 is the second excluded point.

Final answer:

The excluded values are


0,-(8)/(7)
