The goal here is to get the complex number out from under. You can do this by multiplying the denominator by its complex conjugate which is: 3-5i
%282-4i%29%2F%283%2B5i%29+=+%28%282-4i%29%283-5i%29%29%2F%28%283%2B5i%29%283-5i%29%29 = %286-22i%2B20i%5E2%29%2F%289-25i%5E2%29 = %28-14-22i%29%2F%289%2B25%29 = -%2814%2B22i%29%2F34 = -%287%2B11i%29%2F17
