## anonymous one year ago Solve trig equation $$2 sin^2 \theta + sin \theta =0$$ What are the solution sets?

1. Nnesha

factor

2. Nnesha

let sin = x so it's same as (2x^2 + x) now factor

3. anonymous

Ah ok thank you. I see not. So it is like $$2x^2 +1x$$ x = sin

4. Nnesha

yes right x =sin

5. Nnesha

you got it ?

6. anonymous

Yes I got it. Thank you

7. Nnesha

alright np :-)
