Question 39405: I'm not sure if I answered this problem right:
The square of the first consecutive integer plus the square of the third consecutive integer equals 486 more than the square of the consecutive integer. find the integers.
Here's my work:

x^2 +x^2 +4X + 4 = 486 + x^2 +2x +1
2x^2 + 4x +4 = 487 + x^2 + 2x
Subtract x^2 + 2x + 487 from each side
x^2 + 2x - 483 = 0
(x+23) (x-21)
x = -23 x=21
