7 sin2x - 14 sin x + 2 = -5

Answer 1

set it equal to zero

Answer 2

set it equal to zero
move -5 to the right side and then you will have the quadratic equation (solve for sinx)

Answer 3

-5 is already on the right side

Answer 4

note sin x = y and in this way will get a quadratic in y so just you need to solve it and these roots make equal by sin x and try so what will get

hope will help you
