He said the only vertical asymptote is x = 0.

However, I disagree.

I say that x = 1 is another asymptote.

HERE IS MY WORK:

I factored the denominator.

x - x^2 = x(1 - x).

I then set each factor to 0 and solve for x.

One factor is x = 0

I also set 1 - x = 0 and got x = 1 as another asymptote.

My teacher said that I am wrong but gave me credit for trying.

Who is right and why?

Thanks
