Question 840423: Jeremy wrote down two numbers. The product of the two numbers is 12. Their difference is 4. What are the two numbers and how did you figure this out? Answer by hamsanash1981@gmail.com(151) (Show Source):
You can put this solution on YOUR website! let x and y be two number
then x*y = 12
x=12/y
x-y = 4
12/y-y = 4
(12-y^2)/y = 4
12 - y^2 = 4y
y^2 + 4y - 12 = 0
(y+6)(Y-2) =0
y=2 y = -6
When y = 2 then x = 6
When y = - 6 then x = -2
