The correct answer is:
(4-10i)/(29)


Step-by-step explanation:


Given expression:


(2)/(2+5i)


Apply rationalization (multiply and divide by (2-5i)):



(2)/(2+5i) * ((2-5i)/(2-5i) )


Now evalute as follows:


(4-10i)/((2)^2-(5i)^2)


Remember
i^2 = -1



(4-10i)/(4-(-25)) \\ (4-10i)/(29)


Hence the correct answer is
(4-10i)/(29).


-i
