anonymous · Answer

ah ok i was writing in a different form I was writing in a+bi form

yours is right though, this problem isnt requiring that

directrix · Answer

It's good to get in the a+bi form habit.

5/2 ± (√3/2) i

Be sure that the i does not appear to be under the radical symbol because i and square root of i are not the same.
