Factoring trig equations (2) [Pending...]

My question

With an equation of the form 2 `sin^2` x + sin 2x = 0, I need help in determining a first step to solving it.

Relevant page

5. Trigonometric Equations

What I've done so far

Tried to go the route of (2 sin x + ....)(sin x + .... ) but saw immediately it is a no-go.

My hint is to remind yourself of the first formula on this page: Double Angle Formulas
