Find two numbers whose sum is 10 and whose product is 32. use the quadratic formula to solve
--------------------------------------------------------------------------------
Equations:
x+y = 10
xy = 32
---
Substitute for y and solve for "x":
x(10-x) = 32
---
-x^2+10x-32 = 0
---
x^2-10x+32 = 0
-----
x = [10 +- sqrt[100-4*32]]/2
----
x = [10 +- sqrt(-28)]/2
----
x = [10 +- 2isqrt(7)]/2
---
x = (5+isqrt(7)) or x = (5-isqrt(7))
