Answer by TimothyLamb(4379)   (Show Source):
You can put this solution on YOUR website! y = xx
y + x = 1482
xx + x = 1482
xx + x - 1482 = 0
---
the above quadratic equation is in standard form, with a=1, b=1 and c=-1482
---
to solve the quadratic equation, by using the quadratic formula, copy and paste this:
1 1 -1482

the quadratic has two real roots at:
---
x = 38
x = -39
---
the negative root doesn't fit the problem statement, so use the positive root:
---
x = 38
y = xx
y = 38*38
y = 1444
---
answer:
x = 38
y = 1444
