You can put this solution on YOUR website! The squares of two consecutive integers are added.
The sum of their squares is 181.
x^2 + (x+1)^2 = 181
x^2 + x^2 + 2x + 1 - 181 = 0
2x^2 + 2x - 180 = 0
Simplify divide by 2
x^2 + x - 90 = 0
Factors to
(x+10)(x-9) = 0
the positive solution
x = 9 is the 1st integer, 10 is the 2nd (obviously)
