Question

Write a pair of integers whose product is – 15 and whose difference is 8.

Answer 1

There are few pairs of integers whose product is – 15.

e.g. – 1 × 15 

– 3 × 5 

3 × (– 5) 

15 × (– 1) 

but difference of –3 and 5 or –5 and 3 is 8. So the required pair of integers is – 3, 5 and – 5, 3.
