(cos2x)/(sin3x-sinx) = 1

I found this problem and am having an extremely tough time solving it. I gotten down to a quadratic equation a couple of times, but it wouldn't factor. I am really stumped and really need some help. Thanks in advance.

Don't you know how to solve all quadratic equations?

For the final equation I got:

sinx = 1/2

and then I got:

x = (pi)/6 + 2(pi)k

x = 5(pi)/6 + 2(pi)k

(Sorry, I don't know how to make a pi symbol)
