Save yourself a boatload of confusion and potential sources for error by multiplying both sides of your equation by 
, resulting in:
Quadratic formula:
\ \pm\ \sqrt{(-4)^2\ -\ 4(4)(5)}}{2(4)} )
You can simplify this yourself. To verify that the roots are correct, just substitute each of the roots into the original equation:
^2\ -\ 4i\left(\frac{1\,+\,2i}{2}\right)\ +\ 5i\ =\ 0)
You can do the arithmetic yourself and you can also set up to verify the other root yourself.
