Answer 5

4sinxcosx+2sinx-2cosx-1=0
2 sin x(2 cos x + 1) -(2 cos x + 1) = 0
(2 sin x - 1)(2 cos x = 1) = 0

Answer 6

* that's 2 cos x + 1 in the second parentheses

Answer 7

now you have
2 sin x - 1 = 0
and
2 cos x + 1 = 0


solve these 2 equations and you are done

Answer 8

find what cos x and sin x are then you can find the values of x

I suggest you find all values between 0 and 360 degrees
