    \[(\sqrt{5} - 3i) + (-2 + \sqrt{-9}) \implies (\sqrt{5} -2) + (-3i + \sqrt{-9})\]

    Remember : \[\sqrt{-9} = i \sqrt{9} = 3i\]

    So: \[(\sqrt{5} -2) + (-3i + 3i) = ??\]

    i think then \[\sqrt{-9}\]-3i could be written as 0i as \[\sqrt{-9}\]=3i and answer would be only real no \[\sqrt{5}-2\]
