Please advise how to start with the following trigonometric equation:

6*Sin^2(x) - 3*Sin^2(2x) + Cos^2(x) = 0

To be honest, I do not know what is the first steps to start with.

I have tried to start with:

5*Sin^2(x) + Sin^2(x) + Cos^2(x) - 3*Sin^2(2x) = 0

1 + 5*Sin^2(x) - 3*Sin^2(2x) = 0

but from this point I do not see the next steps to be taken.

Thank you for your help!:)
