Let the 2 numbers be 'x' and 'y':
then, x + y = -2
=> x = -2 -y -- (1)
Also, x * y = -5 -- (2)
Put (1) in (2), we have
(-2 -y) * y = -5
-2y -y^2 = -5
y^2 + 2y - 5 = 0
We cannot factorize these numbers easily, so we will have to use the Quadratic Formula to solve this:
y=( -b ± √( b^2 - 4ac )) / ( 2 * a )
=(-2 ± √( 2^2 -4*1*-5 )) / (2 * 1 )
=(-2 ± √(24)) / 2= -1 ± 2 * √(6) / 2=-1 ± √(6)
We can substitute these values into x=-y-2:
x=-(-1 + √(6)) - 2 = 1 - √(6) - 2= -1 - √(6)
x=-(-1 - √(6)) - 2 = 1 + √(6) - 2= -1 + √(6)
Therefore:
x=-1-√(6)
y=-1+√(6)
OR
x=-1+√(6)
y=-1-√(6)

They do not always. The sum of two negative numbers is negative.

There are an infinity of possible answers. Let n be any number. Then select negative (n+1). Their sum will always be negative one and they will have the product -n2 -n
The sum of two negative numbers is going to sum up to a negative number EX:-2+-5=-7
No. The sum of two negative numbers will always be a negative number. If, however, you multiply the numbers, their product will be positive.
