its 4 and 5
Right.
the number are even
so let the first be x
then the second is x+2
x^2 + (x+2)^2 = 41
x^2 + x^2 + 4x + 4 = 41
2x^2 + 4x - 37 = 0
No integer solution
We could tell from the beginning that this problem has no solution
the square of any even integer is even
the sum of two even number is even, but 41 is odd, so NO WAY!
