The expression 2x + 4 - 2x simplifies to just 4. This is because the 2x and -2x terms cancel each other out, leaving only the constant term 4. **

To simplify 2cos(2x) + 2sin(2x), we can use the double angle identities for cosine and sine. The double angle identity for cosine is cos(2x) = 1 - 2sin^2(x) and the double angle identity for sine is sin(2x) = 2sin(x)cos(x). Using these identities, we can rewrite 2cos(2x) + 2sin(2x) as 2(1 - 2sin^2(x)) + 2(2sin(x)cos(x)). Simplifying further, we get 2 - 4sin^2(x) + 4sin(x)cos(x). **
