Like any other polynomial, you judge the number of solutions by the highest degree of the polynomial. This is a second degree polynomial so it has 2 solutions. They are x = +[sqrt(cos x)] and x = - [sqrt(cos x)]. If you graph those on a calculator the positive portion of the graph is above the x axis and the negative portion is below the x axis. It's really cool looking. You should graph it to see.
