this seems to be an interesting question which has the same answer as

two times number of positive solutions of

4|(x-2)(x-4)|=|sin x|

Now can you try?

Also check zero.. that may contribute to one root!

There will be 8..

I dont know if you guys have doubled the final answer(for the number of +ve roots)?? because there is a |x| involved
