Two numbers have a product of 45 and a difference of 12.
What are these two numbers?
----------------------------
Equations:
xy = 45
x-y = 12
----
x = 12+y
---
Substitute and solve for "y":
(12+y)y = 45
y^2+12y-45 = 0
---
(y+15)(y-3) = 0
y = -15 or y = 3
---
If y = -15, x = -3
----
If y = 3, x = 15
==============================
