I need to find out what two numbers that when multiplied can give me -24 but when added or subtracted can give me -8.
---------------------
Equations::
xy = -24
x-y = -8
-----
x = y-8
-----
Substitute and solve for "y":
(y-8)y = -24
y^2 - 8y + 24 = 0
-------
y = [8 +- sqrt(64-4*24)]/2
-------
y = [8 +- sqrt(-32)]/2
y = [8 +- 4sqrt(2)i]/2
----
y = [4 +- 2sqrt(2)i]
----
Solve for "x".
