Factoring to find stationary points

How do I factor this function?

1/3(2-3sinx-2sin^2x)exp(2/3sinx) to get the answers x = pi/6 and 5pi/6??

The stationary points are not the roots. The stationary points are where the first derivative is zero (0). Preliminary graphing is the best way to select guesses.

Thanks Theodore for your input.
I misinterpreted sin(x)�.
