Question

((x^2+2)/(x^2-1))/((x^2-4)/(x^2-4x-5))
and find the excluded domain

Answer 1

I would suggest doing the math on actual paper but I got
(x^2 + 2)(x-5) / (x+4)(x+2)(x-1) after finding common denominators and simplifying. Tell me if you didn't get this part

Answer 2

The vertical asymptotes are clear now. Set each factor in the denominator to 0 and you see that x=1, x=-2 and x=-4 are discontinuities.

Answer 3

sorry, correction. x=1, x=2, x=-2 are vertical asymptotes.
(x^2 + 2)(x-5) / (x-2)(x+2)(x-1) is the simplified function.

Answer 4

and then identify holes from the non simplified original function.

Answer 5

@nonon I got that but its saying its wrong.

Answer 6

:;( ooh I'm sorry what does it say?
