Hi, I wonder how to solve, and how to get the correct answer\answers to these types of problems:

[tex]2 \sin^2{x} - 4 \cos^2{x} = 0[/tex] [tex] x \in [0°,360°] [/tex]

There are many answers to this. I would really like to know how the correct way to get all of them.

2. Relevant equations

I do not know any relevant equations for this.

3. The attempt at a solution

I have tryed to divide them with [tex]\cos^2(x)[/tex] to get [tex] \tan^2(x)[/tex] But it has not worked.
