Answer:
-7 and -4
Step-by-step explanation:
Simce 11 is a prime number, only 11 and 1 give us eleven and do not add up to give 28 so we find factors of 28 that'll add up to give us negative 11 and multiply to give us 28.
factors of 28: 1,2,4,7,14,28 -1,-2,-4,-7,-14,-28
Remember a positive integer has negative factors as well as a negative value times another negative value gives a positive value.
Two number that add to give -11 will be -4 and -7
