What are the excluded values of x for

A. x = - 9, x = 2

B. x = - 9, x = 0

C. x = - 2, x = 9

D. x = 0, x = 9

To find excluded values you must ignore the numerators and focus on the denominators x^2-7x-18 now take - 18, x^2 must be equal to that so we will put in 9^2 and then theres - 7x thats a hard one so we put in 7*0 which is 0, bye bye - 7x. your answer should be x=0, x=9
