The factor pairs of -30 are (-30 , 1), (-15 , 2), (-10 , 3), (-6 , 5), (30 , -1),
(15 , -2), (10 , -3), and (6 , -5).
None of them add up to 5. So we know that the answer to the question
can't be whole numbers.
With some stronger tools, we find that (8.5208) and (-3.5208) come
pretty close to doing the job.
