Question 683060
the product of two numbers is 442. The sum of the two numbers is 43. Find the two numbers.
-------
Equations:
xy = 442
x+y = 43
-----
Substitute for "x" and solve for "y":
x = 43-y
----
So (43-y)y = 442
-y^2 +43y = 442
-----
y^2 - 43y +442 = 0
(y-17)(y-26) = 0
y = 17 or y = 26
------
Solve for "x":
If y = 17, x = 43-17 = 26
If y = 26, x = 43-26 = 17
