4 sin ² x - 4 sin x + 1 = 0 ?
The quadratic formula doesn't seem to work or I am doing it wrong.
Grouping doesn't seem to work.
I am out of options what am I missing?

It's a perfect square
(2sin(x) - 1)² = 0
The quadratic formula works too, but you have to do
sin(x) = [quadratic formula here]
as the function sin(x) is the "variable" in the quadratic equation.
