Problema Solution
Find two integers that have a sum of -19 and a product of 48. What are the integers?
Answer provided by our tutors
Let 'x' and 'y' represent the two integers.
x + y = -19 follows y = - 19 - x
xy = 48
plug y = - 19 - x into xy = 48
x(-19 - x) = 48

x1 = -3
x2 = -16
For x = -3 we find y = -19 - (-3) = - 16.
For x = -16 we find y = - 19 - (- 16) = -3.
The two integers are -3 and -16.
