Let x be the smallest integer. Since they are consecutive even, they have a difference of 2 between each of them, so the second integer is x + 2 and the third is x + 4. The sum of their squares is 440. Solve for x. x^2 + (x + 2)^2 + (x + 4)^2 = 440 x^2 + x^2 + 4x + 4 + x^2 + 8x + 16 = 440 3x^2 + 12x + 20 = 440 3x^2 + 12x - 420 = 0 3(x^2 + 4x - 140) = 0 3(x + 14)(x - 10) = 0 x + 14 = 0 or x - 10 = 0 x = -14 or x = 10 ANSWER: The numbers are -14, -12, and -10, or 10, 12, and 14.

no the sum of three perfect squares are not the sum of other three perfect squares
However the above expression would hold true for the square roots of three perfect squares as well as true for the cube roots of three perfect squares

Yes ,the sum of three perfect squares is equal to sum of other three perfect squares.
eg
(-a)(-a)+(-b)(-b)+(-c)(-c)=(a)(a)+(b)(b)+(c)(c)
