PLEASE DO NOT TYPE YOUR QUESTION IN ALL CAPITALS. IT IS THE ELECTRONIC EQUIVALENT OF SHOUTING, THEREFORE BOTH RUDE AND ANNOYING.
If the first integer is x, then the next consecutive integer is x + 1.
Two times the square of the first integer: 
23 more than the square of the second integer: ^2 + 23)
These two expressions are equal so:
^2 + 23)
and
, so:
(x + 4) = 0)
Hence:
or
Check:
^2 = 32)
^2 + 23 = 9 + 23 = 32)
Checks.
^2 = 72)
^2 + 23 = 49 + 23 = 72)
Checks.
So the required integers are either -4 and -3 or 6 and 7.
