Answer:
either (2, -7) or (-7,2).
Step-by-step explanation:
Say those two numbers are a and b.
According to the question:
a + b = -5 (*)
and ab = -14
As ab = -14 so b = -14/a
Putting the value of b in (*) we get:
a - 14/a = -5
=> - 14 = -5a
=> + 5a - 14 = 0
=> + (7-2)a - 14 = 0
=> + 7a -2a - 14 = 0
=> a(a + 7) -2(a + 7) = 0
=> (a -2)(a+7) = 0
=> a = 2, -7
When a = 2, b = -14/a = -14/2 = -7
When a = -7, b = -14/a = -14/-7 = 2
So, (a,b) = (2, -7) or (-7,2)
So, the integers are either (2, -7) or (-7,2).
