Very next question, no idea what to do...
I am suppose to factor $2\sin^2x + 3\sin x+1$ .
I figure this is pretty simple so I do $(2\sin x)(2\sin x)+3 \sin x+1$ .
For some reason this is incorrect (not sure why) and they give $(2\sin x+1)(\sin x+1)$ which I did verify gives me the original but I don't know how to get there.
