I think you made a mistake or you missed "two consecutive even integers".

Let the two numbers be x and x + 2.

      x² + (x + 2)² = 724
      x² + x² + 4x + 4 = 724
      2x² + 4x - 720 = 0
      x² + 2x - 360 = 0
      (x + 20)(x - 18) = 0

x = -20 or 18

Thus, the two numbers can be -20 and -18 or 18 and 20.
