    I'm a bit confused... for the sin2x part is it really sin2x or (sinx)^2 -> sin^2x

    \[\large \frac{\sin^2x-sinx-2}{sinx-2} \] like this?

    yeah that would work... it's just like factoring only with trigs attached to it \[\large \frac{(sinx-2)(sinx+1)}{sinx-2}\] cancel like terms and see what happens
