x2 -x(cosθ{exp(iΔ)+exp(-iΔ)})+1=0
Can you plz help me in finding the roots of this equation.

Which variable(s) are you solving for exactly?

iam looking for the values of X.

well then ignoring the steps i took in treating the two other variabels as being equal, eitherway it is still a quadratic in x which is standard to solve.
so in this case, a = 1, b = -cosθ{exp(iΔ)+exp(-iΔ)}, c = 1
