- Solved: Consider the equation 3cos^2x-cos x-4=0. Find all exact . . .
$$3\cos^2x-\cos x-4=0$$ 3 cos 2 x − cos x − 4 = 0 This equation can be viewed as a quadratic equation in terms of $$\cos x$$ cos x Let's replace $$\cos x$$ cos x with a variable, say $$y$$ y, to make it clearer: $$3y^2 - y - 4 = 0$$ 3 y 2 − y − 4 = 0 We then solve this quadratic equation for $$y$$ y
