Answer:
-14 and -2
Explanation:
So first off you have to find two numbers that when multiplied equal 28. 4 and 7? Well, those wouldn't add up to -16. 14 and 2 work best. Now since it is -16 and not 16, both numbers need to be negatives since two negatives equal a positive.
The answer would be -14 and -2.
Hope this helps!
