First note that cos^2 x = 1 - sin^2 x. 2cos^2 x - sin x - 1 = 0. 2(1 - sin^2 x) - sin x - 1 = 0. 2sin^2 x + sin x - 1 = 0. Factorizing, you get (2 sin x - 1)(sin x +1) = 0. 2 sin x - 1 = 0 or sin x +1 = 0 . sin x = 1/2 sin x = -1. Hence, x = 360k+30 or 360k+150 (degrees) or x = 360k+270 (degrees) where k is an integer.
