How the Sum of the Squares of Two Consecutive Even Integers Equals 520
Let the two consecutive even integers be expressed as ( x ) and ( x + 2 ), where ( x ) is even.
Their squares are ( x^2 ) and ( (x + 2)^2 ).

Key Insights
Adding the squares:
[
x^2 + (x + 2)^2 = 520
]
Expanding:
[
x^2 + x^2 + 4x + 4 = 520
]
[
2x^2 + 4x + 4 = 520
]
Subtract 520 from both sides:
[
2x^2 + 4x - 516 = 0
]
Divide whole equation by 2:
[
x^2 + 2x - 258 = 0
]
Now solve the quadratic using the quadratic formula:
[
x = \frac{-2 \pm \sqrt{(2)^2 - 4(1)(-258)}}{2(1)} = \frac{-2 \pm \sqrt{4 + 1032}}{2} = \frac{-2 \pm \sqrt{1036}}{2}

Check perfect square—note: 1036 = 4 × 259, but 259 isn’t a perfect square; however, testing nearby even integers reveals:
Trying ( x = 14 ):
[
14^2 + 16^2 = 196 + 256 = 452
]
Too low.
