Question

Find all solutions to the equation.

7 sin2x - 14 sin x + 2 = -5

Answer 1

set it equal to zero then you will get quadratic equation

Answer 2

Yeah I noticed that but can you show me how you to set it up

Answer 3

\[\huge\rm 7\sin^2x-14sinx+2+5=0\]
add 5 both

Answer 4

to make it easy
let sin(x) x
\[\huge\rm 7x^2 -14x+2+5 =0\]

solve for x :-)
