Given 2 sin theta = (1 - 2 x + 5 x^(2))/( 3x^(2) - 2 x - 1) , the real values of theta in [(-pi)/(2),(pi)/(2)] satisfying this lie in the interval

`[-(pi)/(2),(pi)/(2)]`

`[(3 pi)/(10), (pi)/(2)]`

`[(-pi)/(2), (-pi)/(10)] cup [(3 pi)/(10), (pi)/(10)]`

all above

`theta`

`pi-theta`

`2pi-theta`

`-pi+theta`
