Algebra

(x/x-2)+(x-1/x+1)=-1 So far I was able to get it to x + (x-1) = -(x-2)(x+1) through cross multiplying, but I'm kinda lost with what to do now. Should I convert the right side to a polynomial and add the left side, then bring it all to 1 side so it = 0? Thanks!

verifying trigonometric identities

How do I do these problems? Verify the identity. a= alpha, b=beta, t= theta 1. (1 + sin a) (1 - sin a)= cos^2a 2. cos^2b - sin^2b = 2cos^2b - 1 3. sin^2a - sin^4a = cos^2a - cos^4a 4. (csc^2 t / cot t) = csc t sec t 5. (cot^2 t / csc t) = csc t = sin t
