Two positive numbers have a difference of 4 and a product of 96. What are the numbers
----------------
Equations:
x - y = 4
xy = 96
-------------------
Rearrange to get:
x = y+4
----
Substitute for "x" and solve for "y":
(y+4)y = 96
y^2 + 4y - 96 = 0
(y-8)(y+12) = 0
Positive solution:
y = 8
----
If y = 8 then 8x = 96
x = 12
