You can put this solution on YOUR website! One number is equal to the square of another. Find the numbers if both are positive and their sum is 42.
--------------------
Equations:
x = y^2
x + y = 42
----------------
Substitue for "x" and solve for "y"::
y^2 + y - 42 = 0
(y+7)(y-6) = 0
---
Positive solution:
y = 6
----
x = 42-y = 36
