Hello, i would like to know what is the complex number of :

(a*c*d)×(-e*d+i)/(1-e*c*d^2)

ACDE are strictly positive real constants.
I is an imaginary number.

Thanks you a lot for you help.

it would be

(-acde + acd i)/(1 - ecd^2)
or

-acde/(1-ecd^2) + acd i/(1-ecd^2)

complex numbers are written in the form
a + bi, where a and b are real number coefficients
