Answer 2

x=-5, 7 are the excluded values

Step-by-step explanation:

Excluded values are the values that makes the denominator 0

To find excluded values we set the denominator =0 and solve for x

`x^2 - 2x - 35 =0`

Factor x^2 - 2x - 35

(x-7)(x+5) =0

We set each factor =0 and solve for x

x-7 =0 so x= 7

x+5 =0 so x= -5

x=7, x=-5 makes the denominator 0

So x=7 , x=-5 are the excluded values
