This is only true if you use complex numbers.
Given:
a + b = -4
ab = 14
Then:
a(-4 - a) = 14
-a2 - 4a - 14 = 0
a2 + 4a + 14 = 0
a2 + 4a + 4 = -10
(a + 2)2 = -10
a + 2 = ± i(10)1/2
a = -2 ± i(10)1/2
So the two numbers that meet those conditions would be -2 + i√10 and -2 - i√10

There are no two real numbers that do, but the complex numbers (2 + i) and (2 - i) will.If you want two numbers that multiply to negative 5 and add to positive 4 then: -1 and 5If you want two numbers that multiply to negative 5 and add to negative 4 then: 1 and -5
